These tables comprise only the most common host crystals; numerous Other people exist, which are a lot less frequently utilized.
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 �?usually single crystals (monocrystalline optical materials) �?that happen to be employed as get media for solid-condition lasers. Usually, They may be doped with both trivalent scarce earth ions or transition steel 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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the upper-point out life time.
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。
Not surprisingly, it is extremely fascinating that a presented crystal excellent is created regularly, although distinctive laser patterns might have a distinct sensitivity to content parameters.
g. a skinny disk. As A different instance, Q-switched lasers achieve a better population density in the higher laser amount and they are hence more delicate to quenching consequences and Electricity transfer procedures; for that reason, a lower doping density is commonly appropriate for these gadgets. For top-electric Laser Crystal power lasers, reduced doping densities are often accustomed to limit the density of heat generation, While slim-disk lasers function most effective with very doped crystals. Lots of laser merchandise do not reach the whole efficiency probable because these details have not been adequately labored out.
A number of laser crystal products happen to be demonstrated in which some saturable absorber content is integrated for passive Q switching of a laser.

It is obvious that various purposes result in pretty diverse needs on laser achieve media. Due to this, a broad range of different crystals are made use of, and producing the ideal option is essential for setting up lasers with the best possible performance.

For a variety of good reasons, composite crystals have gotten popular. These have a spatially different chemical composition and may be made with Distinctive shapes.
It may be oriented for near perpendicular incidence with the laser beam, or at Brewster's angle. It could be mounted in a few strong mount which also functions for a heat sink. Larger crystals usually are employed for side pumping e.g. with significant-ability diode bars.
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。
