Which geometry, dopant and doping focus on the achieve medium are most beneficial depend upon numerous variables. The obtainable pump source (kind of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the fabric itself also has some impact. By way of example, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is much more appropriate than e.

Certainly, it is vitally attractive that a supplied crystal good quality is developed constantly, Though various laser designs may have a special sensitivity to material parameters.
The maximum possible doping focus can depend strongly about the host material and its fabrication system.
The host crystal is considerably more than just a way to repair the laser-Lively ions at selected positions in Room. Quite a few Homes with the host materials are essential:
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
Individuals surfaces which can be passed with the laser beam are Typically either oriented at Brewster's angle or have an anti-reflection coating.

The medium should have a read more significant transparency (very low absorption and scattering) while in the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by details on the fabrication procedure.
It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be mounted in a few sound mount which also acts like a heat sink. Greater crystals are generally employed for aspect pumping e.g. with higher-energy diode bars.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
