为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
Which geometry, dopant and doping focus with the obtain medium are most useful depend upon various elements. The accessible pump resource (sort of laser diode or lamp) and also the envisaged pumping arrangement are important components, but the material by itself also has some influence. One example is, titanium–sapphire lasers need to be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with relatively modest pump and laser beam diameter, is a lot more suitable than e.
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。
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 may be used to reliably figure out the the best possible crystal Proportions, doping density and possibly values of more parameters.
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
For quasi-3-level laser get media or maybe three-amount achieve media, 1 often should limit the size to a worth that's too limited for efficient pump absorption, as reabsorption outcomes would otherwise spoil the effectiveness. For side pumping, more concerns arrive into Enjoy; Aside from efficient pump absorption, it is more info necessary to get an acceptable spatial condition of your gain 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。
GWU-Lasertechnik has greater than 30 yrs of working experience in distributing laser crystals. Pick GWU to reap the benefits of our vast understanding As well as in-discipline practical experience!
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be preset in some sound mount which also acts like a heat sink. Greater crystals are frequently employed for side pumping e.g. with large-energy 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。
