“…Also, the thermal properties of laser crystals have great influences on crystal growth and processing. 11,12 Crystals with large anisotropic thermal expansion coefficients are easily cracked during crystal growth and processing when subjected to a large temperature gradient. However, there is a limited amount of information regarding the thermal properties of YAP crystals especially with RE 3+ -doping.…”

Ho: YAlO 3 ͑YAP͒ crystal with large size and good optical quality has been grown by the Czochralski method. Thermal properties of the as-grown Ho:YAP crystal have been investigated by measuring the temperature-dependent, anisotropic thermal expansion, specific heat, thermal diffusion, and thermal conductivity. The results show that Ho:YAP crystal possesses a large anisotropic thermal expansion and good thermal conductivity. The calculated average thermal expansion coefficients along a, b, and c axis are ␣ a = 9.18ϫ 10 −6 / K, ␣ b = 1.94ϫ 10 −6 / K, and ␣ c = 7.61ϫ 10 −6 / K from 293.15 to 770.15 K. The thermal conductivities along a, b, and c axis are up to 11.6, 9.9, and 12.3

The LASER light source, whose name is based on "Light Amplification by Stimulated Emission of Radiation", is the most important device in almost all photonic applications. First built in 1960 [6.1-6.5] it allows the generation of light with properties not available from natural light sources. Modern commercially available laser systems allow output powers of up to 10 20 W for short times with good beam quality and of several kW in continuos operation, usually with less good beam quality. Very short pulses with durations smaller than 5 · 10 −15 s, wavelengths from a few nm in the XUV to the far IR with several 10 µm, pulse energies of up to 10 4 J and frequency stability's and resolutions of better 10 −13 can be generated. The laser prices range from $ 1 to many millions of dollars and their size from less than a cubic mm to the dimensions of large buildings.The good coherence and beam quality of laser light in combination with high powers and short pulses are the basis for many nonlinear interactions, but the laser is a highly nonlinear optical device itself, using nonlinear properties of materials as described in the previous chapters. Therefore, the fundamental laws treated in Chap. 2 for the description of light as well as the description of linear and nonlinear interactions of light with matter in Chaps. 3, 4 and 5 are the basis for the analysis of laser operation and its light properties. Therefore, the theoretical description of laser devices represents an application of these laws and can be presented in this chapter in a compact form. For details the related sections of the previous chapters should be consulted. The different lasers and their constructions, as well as the resulting relevant light and operation parameters, are described and the consequences for photonic applications are discussed. Finally, possible classifications are given and safety aspects are mentioned. For further reading see [M6, M16, M17, M23-M25, M27, M28, M30, M33, M43, M44, M49, M50, M58-M65].
