This is older, but also pretty cool.

I think it would have some real applications for indoor gardening. Using it for regular lighting may cause sunburns.

If these guys could cause a surface to emit preferentially in the band gap frequency of a silicon PV cell, they may be on the way to 70+% efficient solar cells. Pardon me, solar THERMAL cells.

Well, it doesn't matter anyway. Incandescents are being banned. Not only will they have to industrialize their laser, they'll have to pay off politicians to reverse the ban.

In America the "ban" is efficiency related. So if they can get to 50 W for 100W of light they will be OK. I think.
