The most common laser-active unusual earth ions and host media together with some common emission wavelengths are proven in the following desk:
These ions enable the crystal to amplify light-weight with the laser wavelength by way of stimulated emission, when Electrical power is supplied to your crystal by way of 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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the higher-state life time.
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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a skinny disk. As another case in point, Q-switched lasers arrive at an increased population density while in the upper laser stage and so are thus a lot more sensitive to quenching results and energy transfer processes; thus, a reduced doping density is frequently appropriate for these products. For high-electric power lasers, lower doping densities are frequently accustomed to limit the density of heat generation, Though skinny-disk lasers function greatest with very doped crystals. Numerous laser items don't get to the comprehensive general performance probable mainly because these kinds of particulars haven't been effectively labored out.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
For quasi-3-degree laser acquire media or even 3-degree attain media, just one usually needs to limit the duration to a value which happens to be way too brief for successful pump absorption, as reabsorption effects would in any other case spoil the performance. For aspect pumping, supplemental factors arrive into Perform; besides economical pump absorption, it is crucial to get an appropriate spatial condition with the get profile.
Diverse crystalline supplies are really diverse more info about their hardness together with other Qualities, which identify with which strategies And the way conveniently they can be cut and polished with high quality.
For various factors, composite crystals are becoming popular. These Have a very spatially varying chemical composition and can be produced with Unique shapes.
It could be oriented for around perpendicular incidence of your laser beam, or at Brewster's angle. It might be mounted in certain sound mount which also functions as a warmth sink. More substantial crystals are usually used for aspect pumping e.g. with significant-ability 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。
