Properties of Solid-State Laser Materials,ent transition of interest. These characteristics are generally shown by solids (crystals or glass) which incorporate in small amounts elements in which optical transitions can occur between states of inner, incomplete electron shells. Thus the transition metals, the rare earth (lanthanide) series,

Laser Amplifier,s 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 straightforward

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

Heat Removal,f the photons between the pump band and the upper laser level is lost as heat to the host lattice and causes the so-called quantum defect heating; b) similarly, the energy difference between the lower laser level and the ground state is thermalized; c) since the quantum efficiency of the fluorescenc

Mode Locking,f the required pulse buildup time. With the cavity dumping technique, the pulse width can be reduced to a minimum of 1 to 2 ns. The limitation here is the length of the cavity, which determines the pulse length. Ultrashort pulses with pulse widths in the picosecond regime are obtained from solid-sta
