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。
Laser crystals are optical crystals �?ordinarily solitary crystals (monocrystalline optical products) �?which might be utilized as get media for strong-condition lasers. In most cases, they are doped with both trivalent unusual earth ions or changeover metal ions.
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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the upper-condition lifetime.
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。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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。
Several laser crystal materials are already demonstrated wherever some saturable absorber material is integrated for passive Q switching of the laser.
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
For quasi-3-level laser attain media as well as 3-amount achieve media, a single often should limit the size to a worth which can be too limited for economical pump absorption, as reabsorption effects would read more in any other case spoil the efficiency. For aspect pumping, added things to consider appear into Enjoy; besides effective pump absorption, it is crucial to acquire an acceptable spatial form on the obtain profile.

The medium must have a superior transparency (lower absorption and scattering) in the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by facts from the fabrication course of action.
With that concept, 1 does not need yet another saturable absorber crystal, making sure that one particular may well make additional compact Q-switched laser setups with decrease internal parasitic losses. However, undesired Uncomfortable side effects can also occur, for example obtaining undesirable valence states of the concerned ions or Electrical power transfers.
