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：
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。
Of course, it is extremely appealing that a offered crystal quality is manufactured continuously, While distinct laser styles might have a distinct sensitivity to material parameters.
The utmost possible doping concentration can count strongly within the host product and its fabrication approach.
The host crystal is way more than simply a method to repair the laser-Lively ions at specified positions in House. A number of properties from the host materials are very important:
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
All those surfaces that happen to be passed by the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.
Various crystalline products are quite different relating to their hardness as well as other Houses, which figure out with which solutions And the way quickly they may be Lower and polished website with high 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 incredibly large emission spectra drives the development of laser diode pumped ultrafast good-state lasers. With the increase in pulse Strength, peak ability, and repetition price of sound-condition lasers, laser crystals will acquire towards bigger sizes, better crystal high-quality, and controllable vital performance.
