Which geometry, dopant and doping concentration in the obtain medium are most advantageous rely on a number of aspects. The obtainable pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial things, but the material itself also has some impact. For example, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively small 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。
A large floor excellent is obviously critical. Specifications of surface area flatness in many cases are much better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam good quality. Moreover, 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。
A couple of laser crystal elements have already been shown where some saturable absorber content is included for passive Q switching of a laser.

For quasi-a few-stage laser acquire media or even 3-level get media, a single often ought to limit the size to a worth that's too limited for efficient pump absorption, as reabsorption results would or else spoil the general performance. For side pumping, added things to consider arrive into Enjoy; Laser Crystal besides effective pump absorption, it is crucial to acquire an acceptable spatial condition of the acquire profile.
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 many years of expertise in distributing laser crystals. Decide on GWU to get pleasure from our large awareness As well as in-subject practical experience!
There's an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some vital teams 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。
