Soraa lasers show record single-mode power

This was over a year ago, wonder why we haven't seen any in the wild?

This article suggest we may see them later this year...

http://optics.org/news/3/1/12

According to Soraa, the CES demonstration represents the first time that high-power semi-polar and nonpolar InGaN devices – adapted semiconductor structures that are grown in a different crystal plane to “regular” GaN-based lasers and LEDs, and which offer much greater efficiency and versatility – have appeared in the emerging application. In particular, the Soraa approach provides a way to make laser diodes that emit in the green, instead of relying on frequency conversion of conventional infrared emitters.


The direct green diodes remain expensive right now, as they are not yet widely available – although that situation could change this year. MicroVision CEO Alexander Tokman says: “With the market availability of direct green laser diodes expected this year, we are working steadily with our partners to help develop the next generation of consumer, commercial and automotive applications that deliver an unmatched big-screen experience from a tiny package.”

Starts off very good! Turns kinda messy at the end!

Lasers seem to be a technology where companies feel comfortable announcing a new product several years before it reaches the consumer.

lol, yea, it got pretty silly, I did not read through it all...
but some interesting info there, hope to see some good stuff soon, interested in seeing the higher power single mode blue, and green diode of course

It's good to see such news, however this remains a unique laboratory item. They also don't discuss the efficiency, which seems to be a big problem with the green laser diodes currently available, at exorbitant prices..
