Laser crystals are optical crystals �?generally one crystals (monocrystalline optical supplies) �?which might be made use of as acquire media for reliable-point out lasers. In most cases, They may be doped with both trivalent unusual earth ions or transition steel ions.
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 on the achieve medium are most advantageous count on numerous components. The obtainable pump resource (kind of laser diode or lamp) and the envisaged pumping arrangement are very important elements, but the fabric alone also has some influence. One example is, titanium–sapphire lasers have to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with comparatively smaller pump and laser beam diameter, is more appropriate than e.

Of course, it is extremely desirable that website a given crystal good quality is produced constantly, While different laser styles may have a different sensitivity to materials 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。
The host crystal is a great deal more than simply a means to fix the laser-active ions at specified positions in Place. Many properties of your host substance are important:
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。
These surfaces that happen to be passed via the laser beam are Typically 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 a lot more than 30 decades of expertise in distributing laser crystals. Pick out GWU to get pleasure from our vast awareness As well as in-discipline experience!
