Which geometry, dopant and doping concentration with the get medium are most beneficial depend on several factors. The available pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are very important aspects, but the fabric by itself also has some influence. For example, titanium–sapphire lasers must be pumped with significant intensities, for which the form of a transversely cooled rod, operated with comparatively compact pump and laser beam diameter, is more acceptable than e.

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。
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-a few-stage laser obtain media or perhaps a few-degree gain media, a person typically must Restrict the size to a worth which can be too limited for effective pump absorption, as reabsorption outcomes would or else spoil the general performance. For facet pumping, extra things to consider occur into Engage in; In addition to efficient pump absorption, it is crucial to acquire a suitable spatial click here form in the gain profile.
Distinctive crystalline resources are extremely distinct regarding their hardness and also other Homes, which determine with which methods And exactly how easily they may be Lower and polished with top quality.
GWU-Lasertechnik has much more than thirty many years of working experience in distributing laser crystals. Select GWU to get pleasure from our large awareness As well as in-subject practical experience!
It may be oriented for close to perpendicular incidence of your laser beam, or at Brewster's angle. It could be set in certain sound mount which also acts like a heat sink. Larger sized crystals are usually employed for aspect pumping e.g. with substantial-ability diode bars.
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。
