Which geometry, dopant and doping focus from the obtain medium are most useful depend upon numerous things. The out there pump resource (style of laser diode or lamp) and also the envisaged pumping arrangement are very important things, but the material by itself also has some influence. As an example, titanium–sapphire lasers must be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with reasonably compact pump and laser beam diameter, is much more acceptable than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
A large area top quality is not surprisingly essential. Technical specs of surface area flatness are often a lot better than . This helps to stop the two scattering losses and wavefront distortions that may degrade the laser's beam good quality. On top of that, scratch and dig specs
The maximum possible doping concentration can rely strongly about the host product and its fabrication method.
The host crystal is far more than simply a way to repair the laser-Energetic ions at selected positions in Place. Several properties on the host materials are crucial:
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。
All those surfaces that happen to be handed because of the laser beam are Usually possibly oriented at Brewster's angle or have an anti-reflection coating.

For several explanations, composite crystals are becoming well-known. These Use a spatially different chemical composition and can be produced with Particular designs.
It could be oriented for in the vicinity of perpendicular incidence of the laser more info beam, or at Brewster's angle. It can be mounted in a few sound mount which also functions as a warmth sink. Larger crystals are generally employed for facet pumping e.g. with higher-electricity 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。
