Blu-ray laser pointer aka 405nm

[HeroesXVillains]

We all know about the classic red laser pointers that you can buy at the dollar store. I've recently built a high powered Blu-Ray laser on my spare time. It can burn paper, pop balloons, write on glow in the dark objects, light matches and much more. Its of the 405nm *nano meters* so its violet, not actually blue which is around 473 nm's, thus having a lot of people being mislead into thinking blu-ray is actually blue.

 

I built my laser from an Xbox HD DVD Drive which is the external one. It runs on 3 AAA's at around 5 volts.

 

It's much stronger then the laser pointers that you get at the dollar store.

Its power measured in Milli-watts is around 90-100mW. I'm running the driver for it at a safe 110 milli-Amps so the laser diode will last longer.

 

I have videos of me playing around with a glow in the dark board and burning some matches.
