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。
This is a snap to perform: just find the lock icon in front of the URL during the address bar and drag that to your bookmark toolbar Using the mouse. In the event you locate the bookmark entry as well lengthy, you may right-click it to edit the text, e.g. making use of "RP Enc" in place of "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
A superior surface area excellent is of course crucial. Requirements of area flatness are often much better than . This assists in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam excellent. In addition, scratch and dig technical specs
The most achievable doping focus can rely strongly over the host content and its fabrication method.
Laser modeling and simulation can be employed to reliably ascertain the the best possible crystal dimensions, doping density and possibly values of supplemental 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。

The medium must have a higher transparency (low absorption and scattering) from the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the caliber of the fabric, determined by facts in the fabrication system.
With that concept, a here single will not need to have an extra saturable absorber crystal, to ensure that one particular may possibly make far more compact Q-switched laser setups with reduce internal parasitic losses. However, unwelcome Unintended effects may arise, like getting undesirable valence states of the included ions or 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。
