4 W 450 nm laser diodes + 750 mW single-mode variants!

A while ago, Pullbangdead mentioned (on PL) that a startup company called Soraa has managed to create high-powered single-mode laser diodes.

Well, Soraa has recently developed a 4 W blue laser diode, as well as a 750 mW single-mode version.

I hope it won't be too long until these hit the market!

Unless someone like C4sio puts these in a new projector or something, it's very unlikely that the diodes will be affordable..

"The compact laser diodes will be used in bulb-free projection displays for use in boardroom presentations, in education, home theatres, and in cinemas."

We just may be in luck :)

I wish someone would release some yellow diodes :(

OH ****ing hell 4 watt diodes being used in handheld lasers. We have to be careful or this will be the thing that gets lasers banned when some moron sets his house on fire with a paper.

Lol.

Yeah, I must admit 4W is a little overkill. I know this will probably never happen, but is anyone else paranoid that one day you'll just be walking and all the sudden you'll get blasted in the face with one of these laser beams? :confused:

Also, lol @ this :knight:

In theory if these things ever come out shouldn't we be able to over drive them to maybe 6W like the 2W 445 dioides? Since they're both made to be used in projectors they must both have some tolerance for higher current.

I'm hoping the beam specs will be atrocious. I honestly don't want such high powered diodes ending up in some kiddies hands.

^^^Ditto

NO ONE needs 4W.. not even in the laser hobbiest side of things.

A laser professional? Perhaps for a show.. or perhaps for a video projector? lol

Single mode 750mw of single mode would be pretty although.

One thing is for sure, high powered RGB's are going to be a lot nicer soon.

I would be excited about a 750mW single mode at 450nm. Slightly more blue shift, in a narrow beam. :D

Lets just pretend some company wanted to put these in projectors today.

How long are we talking until these make it to mass-market (The single mode 750mw one)?


Would it take longer than 5 years?

These 4W diodes sound scary powerful, but I could find some use for em. One of my projects calls for 4 to 5 A140 diodes, a couple of these would be easier to work with and down size it too!
Don't you think they would try to get them to market asap and sooner or later the price would be well worth harvesting?
