green diode






If you can buy a green laser diode, let me know, also, you'll need to take out a loan A huge one

Green laser diodes aren't yet publicly available basically.

They do exist though they are not mass produced or used in any commercial device. You'll need to contact the manufacturers directly to obtain one. They're still sorta in development, so they'll likely be really weak and multimode.

Expect to pay something ridiculous like $10,000 for a 5mW, in minimum orders of 100.

as I said, not publicly available ;D
 
Oh well, you can take a green laser pointer and take the -module-, using it for something else. The module contains pump diode, crystals and lenses to produce a beam, and often electrically connects just as you would any other laser diode (mind the lower voltage for IR).

In most green lasers the module is something that comes out as a single 'component' soldered to a driver board.
 
To my knowledge green laser diodes do not exist at all yet, they ere still in development.

Good god!  When do we expect these prices to come down?

Which prices? The price for green laser diodes? Several things have to happen first. First, someone has to make one. Once someone has made one, then they will have to work on making them manufacturable. Once they are manufacturable and repeatable, then mass-production will start for some applications, notably laser displays. The only working green laser diodes were made over a decade ago out of a II-VI semiconductor compund, I think zinc selenide. These were abandoned because they never worked well enough to actually be usable, and over a decade later, they're still not usable.

Now, people are trying to make green lasers diodes out of a completely different material system (indium gallium nitride, a III-V semiconductor), and as of yet, no one on earth has successfully made one work. Once one works, then it'll be off to the races to get them manufacturable and into mass production. Mass production is the only way that these things are cheap. Diodes that we get cheaply are so because they are mass manufactured for other applications, notably optical storage (CDs/DVDs/Blu-ray). Hobbyists are just waiting for the scraps from other laser applications, that's the only way we ever get them cheaply.
