These tables contain only the most common host crystals; several Other folks exist, which are much less regularly employed.
These ions allow the crystal to amplify light-weight for the laser wavelength through stimulated emission, when Power is equipped to the crystal by means of absorption of pump mild (�?optical pumping
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。
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 concentration on the achieve medium are most beneficial depend upon numerous components. The readily available pump supply (sort of laser diode or lamp) as well as envisaged pumping arrangement are essential aspects, but the material alone also has some influence. For example, titanium–sapphire lasers ought to be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with fairly small pump and laser beam diameter, is much more appropriate 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。
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。
g. a thin disk. As One more case in point, Q-switched lasers attain a greater populace density in the upper laser degree and so are hence much more sensitive to quenching results and Electricity transfer procedures; therefore, a reduced doping density is usually appropriate for these units. For prime-electric power lasers, lessen doping densities are often used to Restrict the density of warmth era, While slim-disk lasers operate ideal with hugely doped crystals. A lot of laser goods don't reach the comprehensive performance likely due to the fact these types of particulars haven't been thoroughly labored out.
Several laser crystal components are already shown in which some saturable absorber materials is integrated for passive Q switching of the laser.
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。

GWU-Lasertechnik has in excess of thirty decades of encounter in distributing laser crystals. Select GWU to gain from our extensive know-how and in-area expertise!
It might be oriented for in close proximity to perpendicular incidence with the laser beam, or at Brewster's angle. It might be mounted in a few reliable mount which also acts being a heat sink. Greater crystals are frequently employed for side pumping e.g. with higher-power diode bars.
