These tables include only the commonest host crystals; numerous others exist, which are much less often employed.
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。

Which geometry, dopant and doping concentration in the achieve medium are most advantageous rely upon various things. The obtainable pump supply (style of laser diode or lamp) and also the envisaged pumping arrangement are important components, but the material alone also has some influence. For example, titanium–sapphire lasers must be pumped with significant intensities, for which the shape of the transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is much more acceptable 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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Laser modeling and simulation can be employed to reliably ascertain the ideal crystal dimensions, doping density And perhaps values of additional more info parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

Unique crystalline supplies are really diverse concerning their hardness together with other Attributes, which decide with which methods And just how easily they are often Slash and polished with high quality.
In 2017, we formulated the whole world’s largest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with particularly large emission spectra drives the event of laser diode pumped ultrafast stable-condition lasers. With the increase in pulse Power, peak energy, and repetition price of solid-point out lasers, laser crystals will acquire toward more substantial measurements, greater crystal quality, and controllable vital general performance.
With That idea, a single doesn't need a further saturable absorber crystal, to ensure 1 may make additional compact Q-switched laser setups with decrease inner parasitic losses. However, undesired Unwanted effects may take place, which include obtaining undesired valence states from the concerned ions or Vitality 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。
