The video shows you how to build a high powered burning violet laser (reason why it says Blue/Violet in title is because half the things you point the violet laser at fluoresce and cause the dot to turn blue)

For written tutorial go here: http://www.spectraforum.com/forum/showthread.php?t=2255

Parts List:
PHR-803T sled-

(You can sometimes pick up the sleds for ~$25 in Group Buys on laserpointerforums.com)

100mA Driver- http://rkcstr.googlepages.com/micro-drive

Aixiz Module-

Helpful Notes:
For extra output, cut out the plastic on the back of the lens

This set up should yield you just under 100mW of 405nm (violet) light, easily enough to burn.

DO NOT "test" the laser diode by hooking it up to a 9v battery, if you do you will break your laser

NEVER EVER point this laser in yours or somebody else's eyes, the wavelength of this light is more energetic then most visible light so a hit in the eye will damage your eyesight! Also do not stare at the dot from up close with out proper protection, if you stare at the dot too much when burning things your eyesight could get damaged. For protection wear a pair of UV blocking sunglasses that block out all of the violet light.

  • Only >1mW pointers ...

    Only >1mW pointers are illegal, you can import 500mW lab lasers with no problem. You can also import laser diodes legally too, so it should be easy for you to buy laser diodes and build your own lasers.

  • To solder you heat ...

    To solder you heat up the two little solder pads and stick the diode pins in the molten solder before it hardens. If you need pictures PM me when you get signed on to LPF (I'm styropyro there too) and I'll send you some.

  • Hey Styropyro, to ...

    Hey Styropyro, to solder, don't you heat up the component and add the wire so it accepts it? This is what my dad says anyway. And I am trying to sign up on LPF but I don't recieve the confirmation email. Anyway, nice instructional video!

    It has to be the PHR-803T sled, you can get them for about $25 in the group buys going on at laserpointerforums . com if you can wait a couple of weeks.

    Yeah as long as the batteries add up to over 7.25v it will work. If you are using an AA or AA flashlight and it doesn't add up to 7.2v, you can use those 3.7v rechargeable AA or AAA batteries in the flashlight instead.

    Wow, did you basically freeze the diode to get that?

    Acutally it dempends on the temperature. But you are right in general.

    But i really I measured some 390nm radiation! The diode was almost dead at this point.

  • You have to have at ...

    You have to have at least 7.25v to power it, but you could use those AA and AAA sized 3.7 volt lithium batteries in the light instead.

    That will work because those batteries charge to 4.2v a piece.

    What if i take two 3.6 volt rechargeable batts and power it with that. Because it adds up to 7.2 volts. Would that work? Need to know.

  • Can i do that but ...

    Can i do that but put (3) 1.2 volt Rechargeable batts in and power it, or do you need more current? Because you said it needs at least 7.25 volts. I want to put it in a flashlight.

    technically no UV comes from this either, the wavelength of this laser is around 405nm which isn't UV, it's pretty close though.

    No IR comes from these, this is just a diode laser. Basically the only lasers that emit IR are unfiltered green lasers and IR lasers, that's about it for what we can buy.
