晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

A significant surface good quality is certainly crucial. Requirements of area flatness in many cases are a lot better than . This allows to avoid each scattering losses and wavefront distortions which may degrade the laser's beam top quality. Additionally, scratch and dig specifications

The maximum achievable doping focus can rely strongly on the host substance and its fabrication strategy.

The host crystal is a lot more than simply a method to repair the laser-Lively ions at specified positions in space. Quite a few Houses of the host substance are very important:

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。

It is obvious that distinct programs cause incredibly unique prerequisites on laser attain media. For this reason, a wide array of check here various crystals are utilised, and producing the correct selection is essential for developing lasers with ideal overall performance.

Diverse crystalline components are very unique concerning their hardness and various Homes, which determine with which approaches and how very easily they may be cut and polished with high quality.

For different causes, composite crystals are becoming popular. These Have got a spatially various chemical composition and can be made with Exclusive designs.

It may be oriented for near perpendicular incidence with the laser beam, or at Brewster's angle. It might be fastened in certain stable mount which also acts as a warmth sink. Bigger crystals are usually used for side pumping e.g. with significant-power 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。
