These tables have only the commonest host crystals; several others exist, which happen to be significantly less routinely employed.
These ions help the crystal to amplify gentle with the laser wavelength through stimulated emission, when Vitality is supplied into the crystal by means of absorption of pump mild (�?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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-condition life span.
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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The maximum probable doping concentration can count strongly to the host materials and its fabrication method.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。

Various crystalline products are certainly various relating to their hardness along with other properties, which establish with which techniques And just how effortlessly they are often Slash and polished with good quality.
In 2017, we produced the world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with extremely broad emission spectra drives the event of laser diode pumped ultrafast strong-condition lasers. With the rise in pulse energy, peak electrical power, and repetition fee of stable-state lasers, laser crystals will create toward more substantial measurements, higher crystal high-quality, and controllable vital functionality.
There is certainly an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some essential groups of crystals are:
