The commonest laser-Lively scarce earth ions and host media together with some common emission wavelengths are demonstrated in the subsequent desk:
Right here you may post questions and comments. So far as they get approved by the writer, they may appear over this paragraph together with the creator’s response. The author will decide on acceptance determined by certain conditions. Fundamentally, The difficulty needs to be of adequately wide 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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping concentration with the acquire medium are most useful rely on various aspects. The out there pump supply (variety of laser diode or lamp) as well as the envisaged pumping arrangement are crucial elements, but the fabric alone also has some influence. Such as, titanium–sapphire lasers need to be pumped with substantial check here intensities, for which the shape of a transversely cooled rod, operated with comparatively smaller pump and laser beam diameter, is more proper than e.

Needless to say, it is very fascinating that a provided crystal excellent is produced continuously, although distinct laser layouts can have a unique sensitivity to substance parameters.
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。
Several laser crystal elements are shown in which some saturable absorber product is incorporated for passive Q switching of a laser.
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。
Those surfaces which can be passed with the laser beam are Typically possibly 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 much more than 30 many years of practical experience in distributing laser crystals. Pick GWU to take advantage of our wide know-how and in-area expertise!
There is a variety of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline constructions. Some important groups of crystals are:
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。
