The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the higher-condition 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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
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-three-amount laser gain media or perhaps three-stage acquire media, 1 frequently must limit the length to a price that is much too short for economical pump absorption, as reabsorption outcomes would in any other case spoil the overall performance. For facet pumping, further concerns appear into Perform; Other than productive pump absorption, it is important to get an acceptable spatial shape on the attain profile.

The medium must have a large transparency (lower absorption and scattering) inside the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this depends on the read more standard of the fabric, determined by details of your fabrication approach.
With that concept, a single won't have to have yet another saturable absorber crystal, in order that just one may well make extra compact Q-switched laser setups with lessen interior parasitic losses. However, unwanted Negative effects can also take place, like getting undesired valence states in the involved ions or Electrical power transfers.
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。
