You never answered my questions:

I'd like to know operating specs for these items:

9mm 904-915nm CW laser diodes $50.00 lot of 2

9mm 808nm 2W laser diode


Also, are the orange laser diodes 5.6mm cans?
How about $50 for the 125mW one? *


Can I have a sample of the gold solder?
I use 14k gold solder for most of my lasers, and I would like to try this out if you don't mind *

hes asking a lot more for the oj diode than that. *[/quote]
OH NO!!! It's an OJ diode?
What if it kills me? *Shudders*

:P

Yea, I know, but he might accept ;D
[/quote]


LOL, you may even have trouble finding a mount that will fit them

Is the gold solder like a cylinder like normal solder and how thick is it like 1mm, 2mm?

Also how LONG is 1 gram?

Hi heruursciences * ..You said

Quote:
Red 1 Watt 9mm 635nm $150.00 each w/colimator assembly $250.00, with nice TEC cooled collimator assy (custom build), $300 each

Red 1 Watt TO-3 635nm with nice TEC cooled w/collimator assy, $300 each "
Can you post any data sheet on 9mm 1W diode, and pics of its collimator assembly? I cannot find any 1W 9mm diodes on Boston Lasers page. Only 100mW!

also,

Can you post picture or dims of TO-3 635nm diode with collimator assembly.

and finally, you sell $25 collimator assembly for 9mm diodes. Is this ready for any wavelength you have 9mm diode to be inserted?

thanks

P.S
I sent you payment, please check your email and PM here, I had additional items request but need info before I pay.

Think paperclip. *A paperclip usually weighs close to a gram, these are the big paperclips I think. *The gold will be more dense, so it will be smaller than a paperclip, but that's a rough estimate. *Maybe about the size of a small paperclip. *Gold is about twice the density of iron, nickel, or copper. So you can take a piece of copper wire, about the size of a paperclip, weigh it, and the same weight in gold will be ABOUT half that size.

Again, rough estimates, but that's about what you're dealing with here.

So you're looking at $25 for maybe about the amount of metal in a paperclip. But if you have an application that needs that kind of stuff, then it's worth that much money. But with the questions you're asking, I doubt it's worth it to you. But maybe the yellow color just really strikes your fancy.

Default Re: RED 635nm 1WATT LASER DIODES and OTHER STUFF C

I'd like to know operating specs for these items:

9mm 904-915nm CW laser diodes $50.00 lot of 2

Up to 2 watts CW up to 4W peak QCW at about 30% duty cycle with continuous on time no more than 8 milliseconds, 2.2A for CW and 4.5A for QCW.

9mm 808nm 2W laser diode.

Up to 2 watts CW 2.2A for CW, if using BRASS mounts such as mereidth instruments modules derate to 1.5W max and limit DC to no more than 15 seconds ON and a minute off for longer life. If using aluminum or copper mounts with adiquite cooling so the diode temp does not go above 125 deg F go nuts with full power.

All 9mm laser diodes are limited to about 2W maximum CW power because of heat sinking issues. The c-mounts can be driven hard because they have good heat sinking.

Also, are the orange laser diodes 5.6mm cans?
How about $50 for the 125mW one?


Price is too low, As far as I know, this laser diode is nearly unobtainable technology and I only have 3 working units. They are in a large metal block package similar to that used for a laser diode bar.

Can you post picture or dims of TO-3 635nm diode with collimator assembly.

and finally, you sell $25 collimator assembly for 9mm diodes. Is this ready for any wavelength you have 9mm diode to be inserted?


I will post the 9mm/TO3 collimator assembly It needs an external mount to be used with 9mm diodes, but I have the flange to use with TO-3 units. I would be willing to include one free with the TO-3 lasers I sell since i found a lot of them.

So you're looking at $25 for maybe about the amount of metal in a paperclip. But if you have an application that needs that kind of stuff, then it's worth that much money. But with the questions you're asking, I doubt it's worth it to you. But maybe the yellow color just really strikes your fancy.

The gold solder is very pale yellow in color, almost the color of white gold alloy used in rings. You'll get a roughly1x2 inch strip of very thin metal. It has strength comparable to brazing but at solder temperatures. It was used to bond diode laser diamond crystal heat spreaders on to the copper mountings. Such lasers done this way could be run at exceptionally high powers for the emitter size, for example a traditional 1W laser diode chip suddenly becomes a 3W emitter, a 25W bar becomes a 60W beast etc.

I thought this was going nowhere, with so much to offer and not enough tech. info. and pictures.


Post as many pictures as possible. Do you have web page of some sort ? How about direct email where we can exchange discuss order detail and insert pictures related to order. Anything would help both parties to get info before paying

I sent you 3-4 PM's and one email(paypal) but pictures are not possible through PMs and no email responses.

again, you have some very interesting components to offer here and I'm sure most of it will sell, but we don't have much info what exactly we are getting.
I would have surely ordered more than just one diode by now.

anyhow, looking forward to seeing those collimating assys for 9mm diodes and more data on 9mm diodes.

cheers

I've never known Heruursciences (Chris) to post too many pics in the past.. I have noticed that he doesn't answer his PMs and such as often as we would like, but I'm sure that he's just busy with these sales. He has an excellent reputation on this forum, and is known for supplying high quality merchandise. You won't be disappointed if you order from him. If I were you, I'd just try looking for information on these components by Googling, in the absence of info from Chris. I'm pretty sure all these items are from an auction selling off the assets of a laser company called Boston Laser. You could find more info by Googling their name as well.. Here's a link to their website:

I don't distrust Chris, I just find it hard to pay hundreds of dollars for parts i want, but can't be sure what is best for me to order.
I did try looking for 1W 9mm 635nm diodes, and it only leads me here. Boston lasers only have 100mW version.
I have to admit I only had time to do quick search and was relying on Crhis to email or post some links of spec sheets.
Collimating assemblies are also important for any lasers and are most critical for multi diode lasers which is why i need to see and know before sending more money.
I don't mean to sound distrustfully. I'm just pushing for more info, so i can order more.
If it was different, i would have placed bigger order and saved few bucks (and my and his time) by now.

cheers all.

I am also trying to get a idea as to what some of these items are also *. I have bought a laser from Heruursciences in the past and had zero problems with the merchandise or shipping . I think he is doing a fine job
I just wanted to make sure of what I was buying for example *- *I was just curious about the : * 4W 904nm laser marking assembly for military target designator $125.00 each .

I did some searches and come up with some info but I am not sure how accurate the info is . There are some pictures of laser markers *: http://www.bostonlaserinc.com/pack7.php

However according to the website it makes no mention of a 904nm marker in the 4w range . So I wonder is that picture representative of the product?

I know sometimes in emails it is easy to misunderstand the context or emotion intended .
I am not angry or upset in any manner shape or form . I am just curious about a item

Thanks Terry *

Sorry for not getting back sooner, I have been pre occupied with some BS over the last couple days. I am tying to resolve a PAY-PAL problem, yesterday the fucktards stole $2700 out of my account for no reason in a transaction that says pending. Don't worry I will get everybody's orders out ASAP anyway. However, I will not accept new orders through paypal for the time being.

The 904nm assembly is a target designator and seek laser for a smart bomb, You will not find any info about it on google. It has a 9mm laser diode with a FAC lens with a 7W 904nm chip on a diamond die heat spreader all in a hermetically sealed little tube collimated into a 1/2 inch laser pointer like beam. Due to the deficiencies in heat sinking 9mm laser diodes i'd only run it at 2W CW output max. It is rated for 4W QCW in target designation service here it is:

I have some of those airborn markers too, you can gut them and replace them with ANY FAC corrected c-mounts.. They have 808nm diodes at 3W inside currently I have a few that are bigger with a phased array attached that produce about 30W at 808nm, 915, and 980nm

Thanks ! That info with the picture really helped in my decision . I did not realize these were 9mm. What I was looking for was a c-mount or a to-3 with about the same specs .
Please correct me if I am wrong. If I order this : “4W c-mount or 9mm 904-915nm CW laser diodes $50.00 lot of 2” and I purchase the c-mount type with one of these “Multimode primary collimator lens set $25.00 each” is this what I need to make it focusable and useable .

I hope you get your Pay-Pal problem solved soon .Dealing with companies like that can be a pain in the *** .When you are able to accept pay-pal or maybe google checkout *please let me know .

Thanks Terry *

The pay pal SNAFU occurred when i bought something yesterday and they double charged FROZE my account. It get's weirder, the company I bough from was local and is trustworthy, has no information on their books about the second charge either on their end or from the credit card processing company. In short due to all the sales from both ebay and this website, I think paypal thought my account was ripe and raped me for not doing strictly ebay. I am about to throw up, this is BULLSHIT!!!!


I will try setting up a Google checkout sometime next week, until then please pause for now on the ordering of stuff or send me a money order or check.


Yes the 4W laser diodes are only 2 for 50.00, you will need an additional cylinder lens to correct the axis the rest of the way.

Other than meredith modules, are there any other cheaper ways to mount a 9mm LD?
