Hello,

So i'm yet another australian who's at risk of being anal probed by customs and i've toiled with this idea for some time now.

To my understanding 532nm lasers use a 808nm Diode and a series of crystals to lase.
What i'm planning to do is buy a 1mW pen locally(532nm) and then order a 300mW or more 808nm Diode from overseas and replace the exsisting diode in the pen, before i do this though i would just like some input from the lpf community and maybe a few pointers(not lasers :p ).

for example do these 1mW pens still use the same Diode > Crystals > Beam Lens'
setup or is there something different and also has anyone had previous luck.

For reference heres the pen i'm planning to purchase: New Stylish Green Lazer Laser Beam Light Pen Pointer 1mW 532nm High Power | eBay

Not only would that be incredibly difficult from a hardware perspective, you would either fracture the crystals or get a very poor return on power invested. You would also need to upgrade the driver and use different cells. You need to upgrade a lot more than the pump diode to get a higher power laser.

tl;dr: NO.

Thank you for the input,

I've managed to get these apart before without visible damage to optics, i did kinda think that i would need to beef up the power supply, what i thought i'd do is put a 300mw 808nm in place of the exsisting diode and if required turn this into a lab style laser using a LM317 driver similar to my profile picture, if everything went perfectly (unlikely for me) would the 300mw diode properly lined up be able to achieve 15-30mw of 532nm?

in my case its more about experimentation then power and i dont think i'd be trying to turn one of these into a 100mw 532nm.

if only people sold Complete crystal sets for the same price of modules or cheapy pens for people to experiment with :(
