200mW of green for $125 shipped!!!!!!!!!!!!! - Laser Pointer Forums

ElektroFreak · 05-15-2010, 06:23 PM

I just bought one of these modules form ebay seller trilights:

TTL: 150MW Green Laser Diode DIY DPSS Module + Power TTL - eBay (item 230459960917 end time Jan-03-11 20:19:28 PST)

The laser was packaged immaculately and was shipped fast, arrived here at my house in 7 business days.

Given the low cost I didn't know what to expect, but the module is actually quite decent. Stays in TEM00 mode so far (I've only tested it for about 2 hours) and the power is very stable at 316mW peak 305mW avg!!!!! (pic later, don't have my phone handy ATM) I had to double-check my meter... thought it might be broken or something.

freaking awesome.. especially for $125..

I can't say for sure that they are always this powerful, but if you're planning on building a scanner or if you just want a lot of green for cheap, these modules are just what you need..

EDIT: the above-mentioned power quote is BEFORE IR filtering. After filtering my unit has a stable output of ~200mW avg. I have revised the title to reflect this. Your mileage may vary.

Sweet! I'm getting me one.

Do you know the divergence?

bloompyle · 05-15-2010, 06:37 PM

If only I had $125..... >.<

lasersbee · 05-15-2010, 06:53 PM

Thanks for the Heads up EF...

just bought one... I'll let you know If I get a Beast like yours...

He IS selling them as 150mW...

Jerry

ElektroFreak · 05-15-2010, 07:17 PM

Very true Jerry, they are spec'd at 150mW.. I hope you do get a beast, but even if they only made 150mW on the nose, $125 shipped for a TEC stabilized module is still a good deal which is why I bought one.. anything more is just a bonus.

EDIT: Missed the divergence question

They have decent divergence, but not awesome. About 1.5-1.8mrad or so.. For laser show applications, this is ideal from a safety perspective. The beam diverges enough so that it isn't nearly as dangerous after a few yards, but the beam is still extremely tight in appearance. It's TEM00 as well and I haven't seen mine mode hop while running CW.

ElektroFreak · 05-15-2010, 08:08 PM

Update: After adding an AR coated IR filter the output drops to 200-225mW, so there's about 100mW of IR in there. IR filtering is recommended, but fortunately the front cover is easily removed with two screws and an IR filter can then be attached across the aperture using epoxy or caulk or even double-backed tape (NO super glue!!!!!). You can get AR coated IR filters quite cheaply here: One piece IR Filter - eBay (item 130384721909 end time May-20-10 06:01:36 PDT)

These are still a great deal for the money.. I do recommend adding an IR filter, but that's quite easily done with these.

Gryphon · 05-15-2010, 08:15 PM

Even 200-225mW of GREEN is awesome for $125, especially considerng its a labby too.

Xplorer877 · 05-15-2010, 09:28 PM

Nice find, but what kind of plug does it have? I don't think that is and American standard wall plug from the pic.

EDIT, nevermind I see that they'll send the appropriate plug based on the shipping address.

This is very cool! I may have to consider this.

brando132 · 05-16-2010, 12:57 AM

**EDIT**Nvm, I got it.

Solonar · 05-16-2010, 01:13 AM

Is it really TEC stabilized, no mention in the ad.

brando132 · 05-16-2010, 01:19 AM

It says so in the PDF manual on the listing. Heres a link-> http://www.storexp.com/ebay/doc/150m...r%20module.pdf

Solonar · 05-16-2010, 03:05 AM

AH, thx. Missed the link.

brando132 · 05-16-2010, 03:09 AM

No problem.

nikokapo · 05-17-2010, 02:05 AM

Hey! It's $99.95 now!!

bobhaha · 05-17-2010, 02:15 AM

Niko that price is with shipping included... $99.95 + $24.00 shipping

Ramsey_innovations · 05-19-2010, 04:46 PM

Elektrofreak, I was wondering what the ambient temp is where your running this laser. I'm interested in getting one but I live in Florida where it is usually in the 90's and dpss modules tend to be unstable. Of course I keep the temp in my house in the mid 70's but that doesn't leave much breathing room. I know the module is TE-cooled but I’m wondering how well.

Lasersbee, I'm anxious to see what the output of yours will be, please post back once you can, thanks!

lasersbee · 05-19-2010, 05:19 PM

I definitely will R_I... it seems they shipped it out yesterday...
so another 10-14 days...

Since these are TEC cooled, as long as you place it on a heatsink (thick metal plate, CPU heatsink) you should be good to run it at any ambient temp. The manual suggests not to run it more than 4 hours in hot environments, but the stability should be unaffected since the TEC keeps the diode at a constant temperature regardless of ambient temp. The problem with hot temperatures is that as the difference in temperature on each side of the TEC gets bigger, the TEC drive circuit needs to provide more and more power, eventually overloading and failing which can cause damage to the laser quickly in a hot environment.

Ramsey_innovations · 05-19-2010, 06:04 PM

Thanks for the quick reply guys. I appreciate the info. I guess I'll be patient and wait to see the output of Lasersbee's before I take the plunge. Thanks again!

lasersbee · 06-01-2010, 08:40 PM

I just received my 150mW Green TEC cooled Laser...

It averages 354mW... It maxed at 361mW... I checked it
on 3 different LPMs...

Jerry

ElektroFreak · 06-01-2010, 09:08 PM

WOW Jerry! That's even more powerful than mine was before filtering. I'd be interested in seeing how yours does with an IR filter on it..

Awsome, thats great news. I'm ordering mine now. Thanks for the quick report lasersbee it's appreciated.

Uranium · 06-01-2010, 10:06 PM

Jesus i wonder what their 500mw one puts out!?

lasersbee · 06-02-2010, 01:42 AM

I'll try it tomorrow with an IR Filter and post back here...

I did notice that the divergence as received was a bit high..
I'll try and find time to test that more accurately as well...
