I want to build my own laser.
However, I am not confident of full DIY
I understand fully DIY is
Take laser diode, insert in copper tubing, put lens in front, then solder driver to the diode and then take apart a flashlight.
However, your 77$ PL450B kit https://sites.google.com/site/dtrlpf/home/diodes/450nm-pl450-diodes seems interesting
With 200mA current what will the laser be? 600-700mW blue?
Once I get this module with driver attached, all I need to do is find a ultrafire,trustfire flashlight, take out the drop in module, and put this module with a heatsink around it?
For heatsink I am thinking of raiding an old motherboard and drilling home in aluminum
I was searching the forum for "Easy way out DIY" thread, but could not find any.
My next build I would like to build a 1w green hand held laser then maybe a 3-4w blue hand held laser.
Wow, ambitious. Unfortunately, both of those are not practical builds right now. A 1W green will set you back about $1,000 minimum, and for a 4 Watt you would need to construct a dual diode system.
3 watts of blue is possible though, with the Nichia 9mm diodes, which are also provided by DTR.
Hey thanks for the input. I am not up on what is feasible or even needed in a hand held laser, but it is an interesting hobby. Along with that keeping safety and responsibility in mind.
Forget that - you're going to blow up laser diodes left right and centre without a driver. The reason that lasers generally use one type of battery are that a driver is easier to design for a smaller input voltage range (i.e. 3-4.5V instead of 3-9V).that has no voltage or wattage regulation.
