The way a LASER Works is Really Cool!
Here we talk about the physics of laser light that it’s monochromatic and has the same wavelength and we use a resonant cavity and and a population inversion to generate the laser light. We also talk about what lasers are actually used for.

Our Laser Communications Relay Demonstration (LCRD) is gearing up for launch this fall, no earlier than Nov. 22 aboard a United Launch Alliance Atlas V 551 rocket. Once in orbit, LCRD will demonstrate the benefits of using infrared lasers to communicate information from space. These benefits include increased data in a single downlink, as well as reduced size, weight, and power requirements for a communications system on a spacecraft. As we prepare for liftoff, learn more about how this technolo
