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。
Additionally, some versatility is missing in experiments if a person can't Check out absorbers with different thickness or doping concentration, one example is, without exchanging the laser crystal alone.
Which geometry, dopant and doping focus with the gain medium are most useful count on numerous aspects. The readily available pump resource (kind of laser diode or lamp) and the envisaged pumping arrangement are crucial factors, but the fabric by itself also has some influence. For example, titanium–sapphire lasers must be pumped with high intensities, for which the shape of the transversely cooled rod, operated with somewhat smaller pump and laser beam diameter, is a lot more suitable than e.
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。
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
The host crystal is way more than just a means to fix the laser-Energetic ions at sure positions in Area. A variety of Attributes from the host content are important:
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
All those surfaces which might be passed via the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.
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 in excess of thirty yrs of working experience in distributing laser crystals. Choose GWU to take advantage of our here vast information and in-field encounter!
It might be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It could be fastened in certain stable mount which also functions as being a heat sink. Bigger crystals are often used for facet pumping e.g. with superior-electric power 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。
