These ions help the crystal to amplify gentle on the laser wavelength via stimulated emission, when Electrical power is provided to the crystal by means of absorption of pump light (�?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。

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：

A high surface area high-quality is obviously critical. Requirements of area flatness are often better than . This aids in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. On top of that, scratch and dig technical specs

g. a thin disk. As One more case in point, Q-switched lasers arrive at an increased inhabitants density within the higher laser amount and are as a result additional delicate to quenching effects and Power transfer processes; for that reason, a lessen doping density is commonly suitable for these devices. For high-electrical power lasers, reduced doping densities are often used to Restrict the density of warmth era, Despite the fact that skinny-disk lasers perform greatest with very doped crystals. Numerous laser goods don't get to the entire general performance prospective since this kind of details haven't been correctly labored out.

The host crystal is far more than just a means to fix the laser-Energetic ions at sure positions in space. Quite a few click here Attributes of the host materials are very important:

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

All those surfaces which might be passed with the laser beam are normally possibly oriented at Brewster's angle or have an anti-reflection coating.

Unique crystalline components are very different relating to their hardness as well as other Houses, which figure out with which procedures and how simply they may be cut and polished with good quality.

For many explanations, composite crystals have gotten common. These Have a very spatially varying chemical composition and will be manufactured with Particular shapes.

With that concept, one does not need yet another saturable absorber crystal, so that one may perhaps make extra compact Q-switched laser setups with lessen inside parasitic losses. Even so, undesirable Negative effects might also manifest, for example obtaining undesired valence states in the associated ions or Strength 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。
