The most common laser-active rare earth ions and host media along with some typical emission wavelengths are revealed in the next table:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
Which geometry, dopant and doping concentration of your get medium are most beneficial depend upon numerous elements. The available pump supply (kind of laser diode or lamp) as well as envisaged pumping arrangement are very important elements, but the fabric alone also has some influence. One example is, titanium–sapphire lasers need to be pumped with high intensities, for which the shape of the transversely cooled rod, operated with comparatively compact pump and laser beam diameter, is much more ideal than e.
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 large area good quality is obviously significant. Specs of floor flatness are frequently a lot better than . This helps in order to avoid both of those scattering losses and wavefront distortions which may degrade here the laser's beam good quality. In addition, scratch and dig specifications
The most doable doping concentration can count strongly about the host content and its fabrication technique.
Laser modeling and simulation can be employed to reliably establish the ideal crystal Proportions, doping density And perhaps values of further parameters.
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。
People surfaces which might be handed with the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
GWU-Lasertechnik has in excess of thirty many years of working experience in distributing laser crystals. Select GWU to gain from our huge knowledge As well as in-field encounter!
It could be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It may be mounted in a few solid mount which also acts being a heat sink. Larger sized crystals usually are utilized for facet pumping e.g. with superior-electric power diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
