These ions enable the crystal to amplify gentle at the laser wavelength by way of stimulated emission, when Power is equipped for the crystal by way of absorption of pump light (�?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 transition cross-sections of pump and laser transitions in addition to the upper-condition 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。
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 thin disk. As Yet another illustration, Q-switched lasers attain a better inhabitants density inside the higher laser amount and are for that reason extra sensitive to quenching effects and Vitality transfer processes; thus, a decreased doping density is frequently suitable for these equipment. For high-energy lasers, decreased doping densities are often used to limit the density of heat era, Despite the fact that slim-disk lasers get the job done finest with really doped crystals. Lots of laser products never get to the full performance opportunity mainly because these kinds of details haven't been effectively labored out.
The host crystal is far more than simply a means to fix the laser-Energetic ions at certain positions in Room. Many Qualities with the host material are very important:
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。

Diverse crystalline supplies are very various concerning their hardness along with Laser Crystal other Qualities, which establish with which procedures and how very easily they may be cut and polished with good quality.
For a variety of motives, composite crystals have gotten common. These Have a very spatially varying chemical composition and will be manufactured with Particular styles.
There's a wide array of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline buildings. Some significant teams of crystals are:
