Is there such a thing as 5mW bluray laser-diode?

[jeffreythe00]

Is there a 780nm diode I think? Also, what makes the 1064nm IR beam in a green laser pointer, prior to it being frequency doubled to 532nm? I thought that there was a 1064nm laser diode behind the KTP crystal?


I took apart a green laser pointer once, and the optical components I found were (in this order) :
near-IR laser diode, crystal, focusing optics. That's it.

Have a look at this thread. It should give you a good understanding on how dpss lasers work.
