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 in the obtain medium are most beneficial depend on several aspects. The offered pump resource (type of laser diode or lamp) as well as envisaged pumping arrangement are essential aspects, but the fabric itself also has some impact. By way of example, titanium–sapphire lasers must be pumped with high intensities, for which the shape of a transversely cooled rod, operated with comparatively tiny pump and laser beam diameter, is more acceptable than e.
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a wide range of technical specs. Moreover the effectively-proven supplies, progressive crystals with remarkable Attributes like Yb:CALGO can open new horizons for demanding laser applications. Regardless of no matter if personal items for R & D applications are required or Price-effective numbers in modest, medium or significant batches with in-time supply for your creation line are necessary: GWU’s focused support really helps to find the finest core components for the application.
A substantial surface area high quality is not surprisingly critical. Specs of area flatness tend to be much better than . This allows to stay away from both equally scattering losses and wavefront distortions which may degrade the laser's beam high-quality. Additionally, scratch and dig technical specs
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 way to repair the laser-active ions at certain positions in Area. Numerous properties of your host substance are very important:
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。

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 thirty yrs of expertise in distributing laser crystals. Opt for check here GWU to take pleasure in our wide information and in-discipline practical experience!
With That idea, a single would not need to have a further saturable absorber crystal, to ensure that a person may well make extra compact Q-switched laser setups with decreased interior parasitic losses. Having said that, unwanted Uncomfortable side effects may also arise, such as getting unwanted valence states in the associated ions or Power transfers.
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。
