Laser crystals are optical crystals �?typically single crystals (monocrystalline optical supplies) �?which might be used as achieve media for stable-point out lasers. Normally, These are doped with either trivalent rare earth ions or transition steel ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the upper-point out lifetime.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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。
Laser modeling and simulation can be used to reliably identify the ideal crystal dimensions, doping density And perhaps values of further parameters.
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-a few-amount laser achieve media or simply 3-degree obtain media, one normally needs to Restrict the duration to a value that is too shorter for economical pump absorption, as reabsorption results would if not spoil the general performance. For facet pumping, more issues occur into play; Other than effective pump absorption, it can be crucial to obtain a suitable spatial form of your acquire profile.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium ought to have a significant transparency (minimal absorption and scattering) within the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this is determined by the caliber of the material, determined by information from the fabrication method.
With That idea, just one isn't going to need to have a further saturable absorber crystal, making sure that 1 could make much more compact Q-switched laser setups with decreased inner parasitic losses. Nonetheless, unwanted side effects can also come about, for example acquiring unwelcome valence states of the involved ions or Electrical Laser Crystal power transfers.
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。
