Optical Pump Systems,the radiation with minimum losses from the source to the absorbing laser material, and creates an inversion which spatially matches the mode volume of the resonator mode. In this chapter we will review the most common pump sources and radiation transport systems employed in solid-state lasers.

Mode Locking, 10–20 ns for most systems. With the cavity dumping technique, the pulse width can be reduced to a minimum of 1–2 ns. The limitation here is the length of the cavity, which determines the pulse length. Ultrashort pulses with pulse widths in the picosecond or femtosecond regime are obtained from soli

Nonlinear Devices, sources. In 1961, Franken and coworkers detected ultraviolet light at twice the frequency of a ruby laser when the beam was propagated through a quartz crystal [10.1]. This experiment marked the beginning of an intense investigation into the realm of the nonlinear optical properties of matter.

Optical Resonator,The radiation emitted by most lasers contains several discrete optical frequencies, separated from each other by frequency differences which can be associated with different modes of the optical resonator. Each mode is defined by the variation of the electromagnetic field perpendicular and along the axis of the resonator.
