These tables comprise only the most common host crystals; a lot of others exist, that happen to be less regularly utilised.
These ions enable the crystal to amplify light-weight with the laser wavelength by way of stimulated emission, when energy is provided towards the crystal by using absorption of pump mild (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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 and also 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 One more case in point, Q-switched lasers attain an increased inhabitants density inside the higher laser stage and they are consequently far more sensitive to quenching results and Strength transfer procedures; hence, a lower doping density is frequently suitable for these units. For high-power lasers, decreased doping densities will more info often be utilized to limit the density of heat generation, although thin-disk lasers do the job greatest with extremely doped crystals. A lot of laser merchandise don't reach the comprehensive functionality probable mainly because this sort of details have not been effectively labored out.
The host crystal is much more than just a means to fix the laser-active ions at specific positions in Room. A variety of Attributes of the host material are 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。
It is apparent that various apps cause quite distinct demands on laser obtain media. For that reason, a broad vary of various crystals are employed, and making the ideal alternative is essential for developing lasers with ideal performance.

For numerous reasons, composite crystals are getting to be well known. These Use a spatially varying chemical composition and can be designed with Specific shapes.
It may be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also acts like a heat sink. Larger crystals are often used for facet pumping e.g. with significant-electrical power diode bars.
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。
