Greetings, new to this site. I have a BeamQ 200MW rifle sight laser. Can't verify if it is a true 200mw. I have it on my 12 gauge shotgun and it holds zero and fully adjustable. Is there anyone in here that could build me one of more power. I could send mine to you for verification and modification. It takes either a CR123 or a rechargeable 16340 batt. It projects a strong beam and dot but want to see what upgrades are available. Also exploring a blue one. In Upstate NY its cold now so I have to rubber band a small hand warmer around the front of the laser, just forward of the wind/elev caps to keep it warm. It works just fine like that. If there is such a person what would the cost be? Thank you kindly.High Power 200mW Green Laser Rifle Sight 1.jpg

If you want something more powerful than 200 mW of green light, its probably not actually 200 mW or you want something that really is incredibly bright.
200 mW of green should be very visible even in direct sunlight at the ranges you're likely to be using your shotgun.

I'd advise against blue for a gun sight because it washes out in bright sunlight. Red and green are much more crisp during the daytime and so are much better for targeting. Intense blue light is also very hard on your eyes and can cause fatigue and temporary depletion of your photoreceptors.
A blue laser with sufficient power to show up clearly during the day will be a hazard to you because even partial reflections will be extremely dangerous for your eyesight.

As for upgrades and testing... I could probably do it but I wont offer just because I dont have the time. I'm working on a sight for my 1911, actually.

Replacing the DPSS module with a diode laser will likely resolve the issue with the cold. I find that 150 mW of 638 nm red is great in all outdoor conditions and works well in cold temperatures. Green diodes are expensive and not designed for that kind of power except for diodes with poor beam quality (rectangular profile and high divergence). Red wont be brighter than what you have now, however.
 
Making a super powerful gun laser might not be a good idea and might not be legal. High powered lasers also have horrible beam specs and the "dot" will look like a bar at longer distances. But it is possible.

A higher powered laser will also be super obvious to any animal downrange, might unintentionally give away your position. (assuming you are hunting)

Anyway, If the laser is not working well in cold conditions then it's probably a DPSS laser. If it's bothering you, there is a fix for that, Direct-diode green lasers. Someone here can probably build that for you. A sharp 520nm single mode pushed to 200mW would work wonderfully. Heck, make it a 488nm diode for some sweet sweet cyan light.
 
Thank you kindly for the replies. If there is someone who can do the second response please let me know.

Stay safe all!
 
I use the 5mw green laser in Call of Duty mobile and I can see it fine in daylight. Even in the snow map . 😁 I can’t offer any help, I’m just trying to get my post count up so I can post links n stuff (noob).

I can't assist nonsense. Are you actually comparing a video game to real life?

My apologies Dud445 was meant for Gatrezal. I wasn't watching the reply to box.

On a related note, how do manufacturers ensure that the laser diodes are not destroyed by the muzzle blast? I've always wondered that, especially since my DIY lasers get crap all over the diode windows and eventually just get destroyed. Are diodes inherently fragile or is it a protective lens/shock-proof casing that does it?

Hi,
I wouldn't worry about the excess gas from the muzzle , I would be more worried about the recoil .

I have seen so many things like that in my life, and they annoy me so much. Since I was little, different guys have been trying to get my attention with this kind of toy, but they don't know the actual power of such lasers.
