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。
In addition, some versatility is dropped in experiments if a single can not try out absorbers with diverse thickness or doping focus, for instance, without exchanging the laser crystal itself.
Which geometry, dopant and doping focus on the obtain medium are most advantageous rely upon a number of components. The available pump source (kind of laser diode or lamp) plus the envisaged pumping arrangement are essential components, but the material by itself also has some influence. For instance, titanium–sapphire lasers must be pumped with high intensities, for which the shape of a transversely more info cooled rod, operated with rather little pump and laser beam diameter, is 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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The most possible doping concentration can depend strongly about the host product and its fabrication method.
A few laser crystal elements are already demonstrated where by some saturable absorber content is incorporated for passive Q switching of the laser.
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。

GWU-Lasertechnik has in excess of 30 decades of knowledge in distributing laser crystals. Opt for GWU to take advantage of our vast awareness and in-subject encounter!
With That idea, a single does not need an additional saturable absorber crystal, to make sure that 1 may perhaps make more compact Q-switched laser setups with decreased internal parasitic losses. Having said that, undesirable Negative effects may also manifest, for instance obtaining unwelcome valence states in the concerned ions or Power transfers.
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。
