These tables incorporate only the most common host crystals; numerous Many others exist, which happen to be less commonly made use of.
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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

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 span.

Needless to say, it is extremely appealing that a specified crystal top quality is produced persistently, although diverse laser layouts can have a distinct sensitivity to product parameters.
g. a skinny disk. As A further instance, Q-switched lasers get to a greater population density inside the upper laser amount and are as a result far more delicate to quenching outcomes and Electrical power transfer procedures; therefore, a reduce doping density is often appropriate for these devices. For high-energy lasers, reduced doping densities in many cases are accustomed to limit the density of heat generation, although thin-disk lasers work best with highly doped crystals. A lot of laser items never get to the total functionality prospective since this kind of particulars haven't been adequately worked out.
The host crystal is considerably more than just a method to fix the laser-Lively ions at specified positions in Area. Many Homes of the host substance are essential:
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。
In 2017, we developed the entire world’s most significant Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the rise in pulse Electricity, peak electric power, and repetition amount of solid-condition lasers, laser crystals will produce toward more substantial dimensions, bigger crystal quality, and controllable essential check here effectiveness.
It may be oriented for near perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in some solid mount which also functions being a heat sink. Larger crystals tend to be employed for side pumping e.g. with large-energy diode bars.
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。
