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。

Laser crystals are optical crystals �?normally one crystals (monocrystalline optical components) �?which happen to be employed as attain media for sound-condition lasers. In most cases, They can be doped with both trivalent rare earth ions or changeover metal ions.

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 of the obtain medium are most advantageous depend upon various components. The readily available pump supply (sort of laser diode or lamp) and also the envisaged pumping arrangement are important variables, but the material alone also has some affect. For instance, titanium–sapphire lasers ought to be pumped with significant intensities, for which the shape of a transversely cooled rod, operated with comparatively little pump and laser beam diameter, is a lot more proper than e.

Obviously, it is very fascinating that a provided crystal quality is generated constantly, although distinctive laser patterns might have another sensitivity to substance parameters.

g. a skinny disk. As An additional case in point, Q-switched lasers achieve the next population density while in the higher laser amount and they are consequently more sensitive to quenching results and Electricity transfer procedures; therefore, a reduce doping density is usually appropriate for these units. For prime-energy lasers, reduced doping densities are sometimes accustomed to limit the density of heat generation, Even though skinny-disk lasers perform ideal with hugely doped crystals. Several laser items don't get to the whole effectiveness likely since this kind of information haven't been adequately worked out.

The host crystal is considerably more than simply a method to repair the laser-Lively ions at particular positions in Room. Many properties in the host product are important:

Those people surfaces which might be passed by the laser beam are Commonly 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。

In 2017, we made the whole world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of here Yb and Tm doped GdScO3 laser crystals with very huge emission spectra drives the event of laser diode pumped ultrafast strong-condition lasers. With the rise in pulse Electrical power, peak energy, and repetition charge of stable-point out lasers, laser crystals will establish towards much larger dimensions, bigger crystal quality, and controllable key overall performance.

There is certainly a wide array of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some crucial 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。
