Lasers. After having derived the quantum mechanically correct suszeptibility for an inverted atomic system that can provide gain, we can use the two-level model to study the laser and its dynamics.

to do with optical devices and optical communications. Laser stands for light amplification. by stimulated emission of radiation, which is a bit unclear. But what it really means is that a laser. is an optical amplifier. That means we have a small signal of light going in, a small amplitude light.

There is hardly a field untouched by the laser. But what exactly is so unique about lasers that makes them so effective? This brief video course is designed for engineers, scientists, medical personnel, managers, and others who work with lasers and/or fiberoptics, or who anticipate working with lasers and/or fiberoptics, yet have little or no ...
The Idea of laser. The change of incoming photon flux, F, is determined by both stimulated emission and absorption. The material behaves as an amplifier (i.e., dF/dz > 0) if N2 >g2N1/ g1 , while...
