These tables have only the most common host crystals; several Other individuals exist, that happen to be significantly less commonly used.

These ions empower the crystal to amplify gentle on the laser wavelength via stimulated emission, when Power is supplied into the crystal by means of absorption of pump gentle (�?optical pumping

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 also the upper-point out life span.

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。

g. a skinny disk. As A different case in point, Q-switched lasers arrive at the next population density in the higher laser level and they are thus much more delicate to quenching effects and Vitality transfer processes; hence, a decrease doping density is commonly appropriate for these units. For high-power lasers, decreased doping densities are sometimes used to limit the density of heat era, While skinny-disk lasers work most effective with remarkably doped crystals. Several laser products and solutions tend not to get to the comprehensive effectiveness potential due to the fact this sort of information have not been effectively worked out.

The host crystal is far more than simply a way to fix the laser-Energetic ions at selected positions in House. A variety of Houses with the host materials are important:

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

These surfaces which might be handed by the laser beam are Typically both oriented at Brewster's angle or have an anti-reflection coating.

For various causes, composite crystals have become well-liked. These Have got a spatially varying chemical composition and will be created with Particular shapes.

There's a wide range of crystalline media, which can be grouped get more info according to big atomic constituents and crystalline structures. Some essential groups of crystals are:

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。
