Powerful Mini Green Laser Build
Here’s another fantastic tutorial from Jay, a DIY lasers expert. See all of our DIY Laser Projects. I modified this very nice Stainless Steel flashlight into a 50mW green laser. It is very heavy duty, and super small. Below, I will show the modifications that have been made to the host and module.
Important: This is a class 3B laser and should be used with care. Proper eye protection for 532nm wavelength recommended. It can instantly damage the eye if it is pointed directly into the eye. Even reflections can cause eye damage.
Here are the pictures that show the modifications:
These are all the basic parts you really need for the project. It’s a super simple setup really, just the laser module, the battery, and housing. That’s it!

The only major modification we have to make is to simply shorten the barrel of the laser. A simple mod to get everything to fit in our steel housing.
Final Results:
It is a very heavy and solid design with good heatsinking for the module. This design offers the option of using CR2 primaries, or RCR2 rechargeable batteries. I am using a CR2 primary and am very happy with the results, so I will not need to push the module with the slightly higher voltage that the rechargeable battery has.

wow,the beam is really strong contrast to its body.I decide to buy a laser diode from http://www.freaklasers.com and do it myself.

Keep in mind, this is using smoke for the beam shot…

I don’t believe so.

Can you use the 130-150mW Module instead of the 50mW? I see from the web site that the 50mW is 57.7mm long and the 130-150mW is 62mm long. So can shorten the 130-150mW module down enough to fit the 49mm length?

Yeah, you should be able to shorten it.

I have a different kit for the normal length modules…
Check that list that I linked a couple of comments above. It is the ‘DIY Green kit’
