being made from different material

and has it working principles

what are laser pointers good for

driver

without chip LM317 your laser diode is gonna burn out

resistor

how to get the laser diode a laser diode is always being found in a dvd set the same spot where'''' you do put in your disc there is a lens under it taking up the lens and dismantle it you would fix complete your burning laser diode and if you don"t care spending you can buy a spoilt dvd set from any electronic engineer you know CAUTION:laser diodes are dangerous burning laser is very dangerous mostly to the eye because lasers can blind you having a laser diode have it own disadvantage that you must know learn to make your own laser diode now
