These tables contain only the most common host crystals; quite a few others exist, which are a lot less regularly used.

These ions empower the crystal to amplify light on the laser wavelength via stimulated emission, when energy is equipped to the crystal by means of absorption of pump mild (�?optical pumping

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-state life span.

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。

Naturally, it is vitally desirable that a presented crystal quality is made regularly, Whilst unique laser models might have a different sensitivity to material parameters.

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 may be used to reliably establish the ideal crystal Proportions, doping density And perhaps values of additional parameters.

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。

It is obvious that different programs produce incredibly distinct specifications on laser gain media. This is why, a wide vary of various crystals are utilised, and creating the proper preference is essential for constructing lasers with ideal effectiveness.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

For many motives, composite crystals are getting to be well known. These Have a very spatially different chemical composition and will be made with Specific designs.

There is a variety of crystalline media, website that may be grouped according to important atomic constituents and crystalline structures. Some crucial groups 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。
