Oh man I miss this site. May be contacting you about the 2.4W 445nm laser soon.

Blord,
Your reputation in the laser community is very impressive!

I am going to buy a laser from you, but I would like your advise which to choose. Burning sounds fun, but isn't my priority. I want the brightest most visible beam no matter what color it is. As far as the host color is concerned, it would be nice to have the host match the beam color, if not blue or black is perfectly fine.

Also I live in the USA and have heard lasers can get caught in customs if they are shipped with batteries. I would prefer to buy everything from you: laser, batteries, charger, and one (maybe two glasses for my wavelength). Please let me know your thoughts, whatever you suggest will more than likely be what I purchase as you are the expert and all I want is something very bright!

Thanks,
Watts

The most visible beam is the 532nm laser. The brightness of the green beam is unmatched. However I can only build a 100mW 532nm laser in the 501B host with a green DPSS module.

Ok so 532 is the brightest wavelength, but what is the brightest laser you can make? I assume 100mW 532 isn't as bright as a 2.2W blue? Am I correct? Either way sign me up for the brightest you have access to making.

Do you know the amount of IR leakage on the green laser you suggested? 532nm 100mW

Very interesting! I don't see that setup on your price list, what would that run? Also I have read about IR needs to be filtered out to be safe. Can you make it with a filter for IR?

I don't have these special diodes in stock but I can build the laser on request.
If I can find a small ir filter for the green DPSS module then that is possible. It is hard to find such small filter. A green laser based on a direct diode don't have IR. The 520nm is such diode.

DTR sells the diode for $120 so the complete laser will be $190.
Shipping is $20

looking for a affordable hand held laser.

In the military and do alot of field training, i am looking for a hand held laser that can light fires. Sometimes when it rains here (ALOT) our matches wont light when trying to build a fire, i was thinking about using a laser for it. Wont be effected by wind/rain and only need batteries. please email me at borg560@gmail.com for some prices and what types in depth you might have that i would be looking for., thanks

lasers have just as hard a time igniting wet material as matches do, though I suppose a laser could be on for longer than a match lasts. are you sure a lighter isn't a more practical solution? you'd need safety glasses as well as the laser to start a fire. lasers capable of igniting say, a stick, need to be stronger than ones that could just blacken it and cause it to slowly smolder. if you dont use nesting material, and need to ignite a stick directly, I'd estimate at least 2W, or pretty close would be needed, which pretty much limits you to a 445nm laser. less power could make an ember in some nesting, which you could carefully blow on to get flame. like I said though, lasers don't ignite wet stuff any more easily.

I doubt this is your best solution, there are wind resistant lighters, like the butane torch ones.

Magnesium rod and striker. Works with soaking wet wood. But hey, if you want a laser go for it!!! I've started a few Bon fires with lasers upon request.
