These tables include only the most typical host crystals; lots of Other individuals exist, that are considerably less often employed.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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 of the acquire medium are most useful rely upon many aspects. The accessible pump resource (kind of laser diode or lamp) and also the envisaged pumping arrangement are very important things, but the fabric alone also has some influence. One example is, titanium–sapphire lasers ought to be pumped with high intensities, for which the form of a transversely cooled rod, operated with somewhat modest pump and laser beam diameter, is much more acceptable 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。
Of course, it's very attractive that a given crystal top quality is produced consistently, although distinctive laser layouts might have a unique sensitivity to substance parameters.
g. a thin disk. As An additional instance, Q-switched lasers access a better inhabitants density within the upper laser degree and are as a result more delicate to quenching consequences and Electricity transfer processes; for that reason, a more info reduce doping density is frequently appropriate for these equipment. For prime-ability lasers, reduce doping densities are sometimes accustomed to Restrict the density of warmth era, Though slender-disk lasers operate greatest with really doped crystals. Many laser solutions will not reach the full functionality possible simply because this kind of aspects have not been properly worked out.
Laser modeling and simulation may be used to reliably figure out the the best possible crystal Proportions, doping density And maybe values of added parameters.
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 are handed because of 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 more than 30 years of encounter in distributing laser crystals. Choose GWU to gain from our wide expertise As well as in-subject encounter!
With That idea, one particular isn't going to need to have yet another saturable absorber crystal, to make sure that a person might make additional compact Q-switched laser setups with reduce internal parasitic losses. Even so, unwelcome Unwanted side effects might also take place, such as getting unwanted valence states on the associated ions or Strength transfers.
