These tables contain only the most typical host crystals; many Other folks exist, which can be a lot less frequently employed.
Below you can submit concerns and reviews. In terms of they get recognized by the author, they may surface above this paragraph along with the creator’s remedy. The writer will choose acceptance determined by specific requirements. Primarily, the issue must be of sufficiently wide desire.
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。
This is not difficult to do: just discover the lock icon in front of the URL during the address bar and drag that to your bookmark toolbar Using the mouse. In the event you discover the bookmark entry much too lengthy, it is possible to ideal-simply click it to edit the text, e.g. using "RP Enc" rather than "RP Photonics Encyclopedia".
GWU offers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) which has a wide range of requirements. Moreover the properly-proven components, progressive crystals with excellent properties like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of whether or not individual pieces for R & D uses are necessary or cost-successful numbers in smaller, medium or huge batches with in-time supply for your generation line are required: GWU’s committed company helps to find the greatest Main parts for the application.
A substantial area quality is needless to say significant. Technical specs Laser Crystal of area flatness tend to be better than . This aids in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam excellent. Also, scratch and dig requirements
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 considerably more than just a means to fix the laser-active ions at specific positions in Room. Many properties in the host substance are crucial:
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。
Those people surfaces which happen to be passed from the laser beam are normally both 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。
For many good reasons, composite crystals have gotten popular. These Have got a spatially various chemical composition and may be produced with Distinctive designs.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in a few stable mount which also functions being a heat sink. Greater crystals are generally utilized for side pumping e.g. with high-electricity 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。
