My DIY Green laser torch

[Diesel]

Hi everyone, this is my first DIY laser torch,
use 1xCR2 or 1xCR123A 3.0v/3.7v lithium battery, it's really portable and **FOCUSABLE**.
Host model: Romisen RC-i3
Output power: >5 to <200 (The LD is changeable so that i can choose the mW as I need)

cut metal thing......heatsink, no machine is used, just a small saw only, and my hands.
I haven't got any equipment to measure the accurate power.

Just wanna share.
Thanks for watching and please don't forget to give me a comment.

Good job! Nice small host for a green...

Tell us more details!

Is is an O-like module?
How did you go about making it a 'focusable' green laser?

Where did you get an adjustable (In terms of power and focal point) green module?

Very nice build.

Thats a really nice build! I'm used to see red and blu-rays only in such compact hosts, so it looks very nice with a green beam coming out.

I'm also very curious about how you achieved a green module that both has adjustable focus and power. Very interesting.

Right, i am uploading the pics right now,
"how does it work?", now let you all know.

This is not an O-like module.
The most difficult thing is cutting the 5mW red diode to fit the host......

there is no suitable green laser for me(in China [Hong Kong]), those MIC lasers are very LARGE and always powered by 18650 battery.
i need a small green laser like igor's, but unfortunately, i DON'T think 18650's green torch is portable! that is why i made it.

Why don't you make a green like this?  I am still looking for a green laser like that.
I think everyone in this forum can do it better than me as well, Igor and you (Jay) especially.

the secrets of my DIY laser are in the pic.

Where did you get that green module? I've never seen one like it before.

Hong Kong......

You may also take the module out from this kinda laser.

I think he got it from a diffrent laser pointer i found one that looked similar in a dx greenie

exacly......I tested at least 40 green modules which are produced in China, 3mins for each one, because i don't trust their quality
and then I’ve got 23 modules…..fail!

Did you cut the green module or the red modules heatsink?
In pic 3 there is 2 heatsinks.If you use the original heat sink of the host then what is the other one is for?
and in pic 4 what is that thing at the end of the LD driver?
What is the performance of CR2 or CR123A batteries for green? I am not pleased with CR2 batteries with my blue laser. you can only play for 3-4 minutes with full power then it decreases.
If it performs well the size is great. If the heatsink is enough for a duty cycle around 5 minutes it is enough for me. Better than a pensize green
Nice work!
