These tables consist of only the most common host crystals; quite a few Other individuals exist, which happen to be significantly less usually made use of.
Here you are able to submit queries and responses. In terms of they get recognized via the creator, they will appear over this paragraph together with the creator’s remedy. The writer will choose acceptance determined by specified requirements. Primarily, the issue needs to be of adequately broad desire.
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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise 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。
Laser modeling and simulation can be utilized to reliably determine the ideal crystal Proportions, doping density and possibly values of supplemental parameters.

The medium must have a significant transparency (reduced absorption and scattering) from the wavelength areas website of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the standard of the material, based on aspects in the fabrication course of action.
With that concept, one does not need yet another saturable absorber crystal, making sure that just one may possibly make a lot more compact Q-switched laser setups with lower interior parasitic losses. Even so, undesirable Unwanted side effects may also come about, including getting undesirable valence states of your concerned ions or Electrical power transfers.
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。
