Can I use the laser from a DVD player?

No, a DVD reader laser is not powerful enough to burn. However, it would make a simple, fun pet laser pointer.

It depends on how powerful the laser itself is. If you can make smoke from a laser, it can light a candle.

Question

Can I hook this up to the PSU or a 9-volt?

GX11 GHOST

Community Answer

It depends on how much your diode requires. If you buy a simple laser diode from an electronic shop for DIY projects, they will give you a diode in brass casing - those can be connected directly to 9-volt. It's a DVD one, you will need a particular circuit.

Question

Can the laser penetrate tungsten?

Alexander Bragg

Community Answer

No, the laser here isn't strong enough. It is more useful to use an actual plasma cutter.

Question

What would be the best diode to use?

Parker

Community Answer

The best diode depends on what you want your laser to do. The best diode for visibility or seeing the beam is any diode with a wavelength closes to 555nm. The best color diode for burning is usually green. Here is a link to a diode that is very visible and powerful.

Question

If I use 4 drivers and diodes and run them all together in parallel, focusing on a singular point, would I need more then one lens to center and focus the beam?

Parker

Community Answer

Technically, yes but your diodes would need to be in a perfect semi-tight circle that you could fit a lens over, or you could use a knife edge laser beam combination to join the beams into a tight line to focus, but that is more work than the first option because you need reflectors, modules, and a large power supply.
