The commonest laser-Lively exceptional earth ions and host media together with some usual emission wavelengths are shown in the following table:
These ions help the crystal to amplify light for the laser wavelength by means of stimulated emission, when energy is supplied on the crystal by means of absorption of pump light-weight (�?optical pumping
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。
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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Not surprisingly, it is very appealing that a presented crystal high-quality is produced constantly, While diverse laser models may have a special sensitivity to content parameters.
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。
Laser modeling and simulation can be used to reliably determine the the best possible crystal Proportions, doping density And maybe values of supplemental parameters.

For quasi-three-level laser gain media or even a few-stage obtain media, one often really should limit the duration to a price which can be as well shorter for efficient pump absorption, as reabsorption effects would or else spoil the performance. For facet pumping, extra concerns occur into Enjoy; Apart from economical pump absorption, it can be crucial to get a suitable spatial shape from the get profile.
Different crystalline supplies are extremely distinct regarding their hardness along with other Homes, which figure out with which techniques And exactly how conveniently they may be Slice and polished with top quality.
For several reasons, composite crystals have gotten well-liked. These Possess a spatially various chemical composition and may be built with special styles.
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be preset in a few strong mount which also click here functions to be a heat sink. Bigger crystals usually are employed for aspect pumping e.g. with superior-energy diode bars.
