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 in addition to the upper-point out lifetime.
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。
The most achievable doping focus can depend strongly to the host materials and its fabrication process.
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。
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。
For quasi-3-level laser gain media or maybe 3-amount achieve media, 1 frequently really should limit the duration to a value which happens to be way too short for successful pump absorption, as reabsorption effects would normally spoil the performance. For aspect pumping, more concerns appear into Engage in; In addition to productive pump absorption, it can be crucial to obtain a suitable spatial shape on the get profile.

The medium must have a higher transparency (reduced absorption and scattering) from the wavelength areas of pump and laser radiation, and here good optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by facts in the fabrication system.
With That idea, just one won't have to have a further saturable absorber crystal, making sure that just one may possibly make extra compact Q-switched laser setups with decreased inner parasitic losses. Nevertheless, unwanted Unwanted side effects may also come about, including getting undesirable valence states of the included ions or Power transfers.
