Laser oscillator,n of two basic components: an optical amplifier, and an optical resonator, which serves to provide highly selective feedback. The optical resonator, comprised of two opposing plane-parallel or curved mirrors at right angles to the axis of the active material, performs the function of the feedback el

Laser amplifier,lse amplifiers is of great interest in the design of high-energy, high-brightness light sources. The generation of high-energy pulses is based on the combination of a master oscillator and multistage power amplifier. For the purpose of illustrating the amplifier concept and principles we assume a st

Optical resonator,ated with different modes of the optical resonator. It is common practice to distinguish two types of resonator modes, “Longitudinal” modes differ from one another only in their oscillation frequency; “transverse” modes differ from one another not only in their oscillation frequency, but also in the

Optical pump systems,he laser material. Electrical current, either continuous or pulsed, is supplied to the pump source and converted into optical radiation. The light source and laser material are contained in a pumping arrangement which concentrates the light from the pump source onto the laser material. In this chapt

Nonlinear devices, sources. In 1961, Franken and coworkers detected ultraviolet light at twice the frequency of a ruby laser beam when this beam was propagated through a quartz crystal. This experiment marked the beginning of an intense investigation into the realm of the nonlinear optical properties of matter
