Organic laser diodes move from dream to reality

Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, ...

Physicists take big step in nanolaser design

Lasers are widely used in household appliances, medicine, industry, telecommunications and more. Several years ago, scientists introduced nanolasers. Their design is similar to that of the conventional semiconductor lasers ...

Is random lasing possible with a cold atom cloud?

(PhysOrg.com) -- Random lasing, Robin Kaiser tells PhysOrg.com, is like standard lasing, with a little bit of a twist: “You don’t know the direction the photons will go, as you do with a more standard laser. This is because ...
