The most typical laser-Lively uncommon earth ions and host media along with some normal emission wavelengths are proven in the following table:
Below you could submit thoughts and comments. As far as they get acknowledged because of the author, they're going to show up higher than this paragraph together with the author’s solution. The writer will settle on acceptance determined by particular standards. Fundamentally, The difficulty have to be of sufficiently broad interest.
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 focus in the gain medium are most beneficial rely on quite a few aspects. The available pump supply (kind of laser diode or lamp) and the envisaged pumping arrangement are very important elements, but the fabric alone also has some affect. For example, titanium–sapphire lasers have 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 much more appropriate 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。
A substantial surface top quality is naturally significant. Specs of area flatness are frequently much better than . This will help to stop both of those scattering losses and wavefront distortions which might degrade the laser's beam quality. Furthermore, scratch and dig specifications
The most achievable doping focus can count strongly within the host material and its fabrication strategy.
A couple of laser crystal resources happen to be demonstrated wherever some saturable absorber material is incorporated for passive Q switching of a laser.
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。
People surfaces which might be handed because of the laser beam are Usually either oriented at Brewster's angle or have an anti-reflection coating.
Unique crystalline products are extremely diverse concerning their hardness along with other properties, which establish with which techniques And just how simply they can be Lower and polished with high quality.
For many good reasons, composite crystals have become more info well-liked. These Have got a spatially varying chemical composition and may be produced with Exclusive designs.
There exists a wide array of crystalline media, which can be grouped according to special atomic constituents and crystalline constructions. Some significant teams of crystals are:
