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。

Furthermore, some overall flexibility is shed in experiments if 1 are not able to Check out absorbers with distinctive thickness or doping focus, as an example, with no exchanging the laser crystal alone.

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

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。

A number of laser crystal materials are actually demonstrated wherever some saturable absorber material is integrated 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。

For quasi-3-degree laser gain media or maybe three-level attain media, one particular usually needs to limit the duration to a price which is way too shorter for economical pump absorption, as reabsorption effects would normally spoil the performance. For side pumping, additional criteria arrive into Enjoy; Apart from efficient pump absorption, it is important to get a suitable spatial condition of your get profile.

Distinct crystalline components are extremely different about their hardness and other Attributes, which ascertain with which procedures And the way quickly they may be cut and polished with top quality.

For a variety of good reasons, composite crystals have gotten well-known. These Possess a spatially different chemical composition and can be made with special designs.

There exists a variety of crystalline media, that may read more be grouped in accordance to important atomic constituents and crystalline buildings. Some vital teams of crystals are:

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。
