Press Release: Direct Injection Green Diode at 531 nm!

This was just posted to the ILDA list server... Have a look!

Direct injection green... No modulation issues, no jellybeaning, no noise! Of course, they'll probably be expensive as hell at first...

Holy cigarette pack sized projectors, Batman! 640, 531 and 445 what a nice combo.

Another nail in the coffin of DPSS devices then - it seems strange to be talking about DPSS as obsolete technology, but it looks as if that's the way things are headed. I wonder how long it will take for these new green diodes to be commercially available.

It's only you Matey.

I'll give you 50 quid for all the obsolete lasers you currently own, can't say fairer than that.

I guess it depends on how much you have invested already in DPSS devices as to how much you agree - but I only said that it looks as if that's the way things are headed, not that they had become obsolete overnight. Personally, I'd love to have an all-diode setup - better stability, better modulation etc etc - but as I've got the best part of a grand invested in my 1W green DPSS laser, I won't be at the head of the queue for a diode replacement - plus they aren't going to be cheap, at least for a while.

I wonder if this new technology can be extended to blue diodes? Maybe we'll see 460/470nm blues?

Well if its anything like 640nm, I doubt it will be any cheaper. As Sororene said in another thread, the price is obviously being kept artificially high on popular colours such as blue and 640 red. After all, diodes usually only cost pence to make and have very little material content due to their small size, so where's the high production costs?
