Tunable lasing at around 405 nm is realised with an InGaN device featuring a narrow-ridge active channel and a periodically ...

That’s where lidar comes in. Like radar, but using light, lidar sends beams from a plane or satellite towards the ground. By measuring the time it takes for the light to be reflected, scientists can ...

The black and white picture shows a bright laser beam being fired from the Preble during a demonstration at sea to verify and validate the "functionality, performance, and capability" of the ...
