I was finding a lot of highly technical info on topics like diode lasers and coherence with Googling, so I posted instead. An idea would be to establish stickies with basic info under the General thread with links that use Flashplayer, like the one I got from SenKat_Stonetek.

What makes diode laser light coherent?

How is divergence measured?

Is 10,000 feet about the range of a true 5 Mw green laser? How about a more powerful 15 Mw?

Are there DIY lasers?

Has anyone ever gotten into trouble for having a >5Mw pointer out-of-doors? I only heard about a few (not very bright) people who shined their pointers into cockpits.

Are laser pointers continuous or pulse?

How many diodes are in a laser pointer? Is there a chamber and mirrors as in other types of lasers with exited electrons and photons interacting?

What kind of device can I use to test laser output?

Does heating cause a laser to reduce output as it is kept on longer?

Can I use the laser continuously?

Hi! I just joined and need a green laser for astronomy. :)

Hi everyone! I Need some buying advice. What 5 mW green pointer uses the best diodes and lens? BTW, how do I know that the 5 mW laser is actually a tad under 5 mW? Can I trust the company specs? Thanks.
