Lecture 20

We model the rate of each process using the Einstein A and B coefficients, and then find when the probability is higher that a photon passing will stimulate emission than be absorbed.

Laser Diode Characteristics and Definitionsf

In a laser diode, the light is emitted because there are both electrons, in the positive substance, and holes (the absence of electrons) in the negative substance.

Anamorphic Shaping of Laser Beams

Examples of laser sources which emit elliptical beams (Fig. 1) are laser diodes and tapered amplifiers. In both cases, the beam shape is due to the flat structures of their active semiconductor layers.
