Hello LPF! Well, I'm going to attempt to build my own burning blue ray laser. I've been doing some poking around on here, and I've come to the conclusion that I need the following.

1) Diode - Looking for a true 150mW (Or better). Been reading, but not sure. Suggestions?

2) Host - Not sure which one to use. Suggestions?

3) Driver - http://hacylon.case.edu/ebay/laser_diode/Micro_FlexDrive.php

4) Lens - http://laserpointerforums.com/f39/fs-405-g-1-glass-lens-mod-28-increase-vs-aixiz-22497.html

Well, feel free to leave me suggestions, except for to buy complete off of someone. I really want to do it myself, to gain experience so that one day I can set the moon on fire with a laser (just kidding). Thanks everyone!!

Unless money and frustration are no problem for you, I would suggest you start with a PHR for your first build. You won't get 150mW, but if you blow one (or more) they are pretty cheap.

Also, a "pen style" is a tougher build that a "flashlight style." The flashlight (or even a box type) gives you much more room for error. Also, there are some very nice (and easy) kits available in the B/S/T section to ease you into the hobby smoothly.

The flexdrive has some pretty small soldering requirements if you want to go over 100mA.

Peace,
dave

Heh figured i would chime in.
1. Diode - For over 150mW, you need a GGW 6x diode which can give you close to 300mW if your using the 405-g-1 lens.
2 & 3. driver and host - Heh...the reason i chimed in. check out these. http://laserpointerforums.com/f39/fs-mxdl-silver-kits-42656.html
4. Lens - Larry and jayrob both offer AR coated glass lens for 405nm lasers. Up to you do decide who to buy from.
-
on top of those things, you'll also need to get yourslef an "Aixiz module", these can be found at modwerx.com for pretty cheap, or even cheaper at aixiz.com if you want to buy ten of them for $25.

Anyways, the diode will go in the aixiz module and the stock acrylic lens on the module will be replaced with your new 405-g-1 lens.

if you need help harvesting your diode and putting it in the module let me know.

As daguin said, I'd suggest getting a PHR-803t for first tries. You may succeed in one try (I hope) but if you kill the diode you'll get experience and you won't miss those $10.00 so much :)

mfo. look here on the forums. hightechdealz.com modworx.com scopeguy20's group buy. also look to see where the selling members are located so that way if they are near you, you can save frieght. like i live in so cal, and meet scopeguy.

I purchased a 100mw green from geareb(ebay seller), about 4 months ago and it is still working well. It is a little bit more than what we usually pay on this forum, but it will be your choice to go with that instead of a PHR for about $10.00. Good Luck!

Here's a rough guide to power vs diode costs:

PHR - 120-130mW - $10/15
GGW - 180-220mW - $55/65
BDRS03 - 280-320mW - $95/115
BDR203 (complete drive) - 300-350mW+ - $180/200

(All quoted specs are before optics, the 405-G-1 lens will give you roughly another 28%)

Alright, I've decided to go with the PHR diode as a first build. How many mA should I set the driver to to get 120mW of output? Is there a reference chart somewhere? Thanks guys.

Hmm, there was a sticky with the reference chart, don't know where it is now though.

~120 mA, although I wouldn't be driving a PHR that high. They're known to die easily.

Really? From what I've read, people have driven them to upwards of 150mA. How many mW would I get at 120mA? I'm guessing around 90 or so?

120 ma will vary from 80-130 more or less these are trippy diodes my favorate

i agree...

last time my current is set to 110mA and im having 100mW only, then i tried replacing the diode.. boom! i got a 130mW at 110mA current.. the old diode i put it on another driver set to 115mA and i got a 110mW lol these PhR's sometimes blows my head off!! heheheheh :lasergun:

Yeah... there are differences in diode efficiency.

I would say that the 'normal' PHR's will give you about 110mW's @ 125mA's through AixiZ acrylic.

Which means right around 140mW's using the 405-G-1 glass lens.

If you go for less current, like maybe 100mA's, you can expect around 85mW's - AixiZ acrylic. (107mW's - 405-G-1)

But since it is only a $10 dollar diode, most push them to 125mA's...

Also, the glass lens is needed when you get to the 6X power or higher. But an acrylic lens will be fine for a PHR build.

Of course, it will still be better with the glass lens, and you will always have it for your future 6X or 8X! :)
