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。
Needless to say, it is rather desirable that a given crystal high-quality is generated continually, Though various laser layouts may have a different sensitivity to substance parameters.
The most attainable doping focus can depend strongly to the host materials and its fabrication system.
The host crystal is much more than just a way to repair the laser-Lively ions at sure positions in Area. Quite a few Houses of the host materials are essential:
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。
For quasi-a few-stage laser acquire media as well as three-stage acquire media, a person typically more info must Restrict the duration to a value and that is also shorter for effective pump absorption, as reabsorption outcomes would or else spoil the effectiveness. For facet pumping, further things to consider appear into play; Apart from successful pump absorption, it is important to obtain a suitable spatial shape in the achieve profile.

In 2017, we created the earth’s biggest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely extensive emission spectra drives the event of laser diode pumped ultrafast good-state lasers. With the increase in pulse Vitality, peak ability, and repetition price of good-point out lasers, laser crystals will develop toward much larger sizes, larger crystal quality, and controllable key functionality.
Using our promotion offer, you may Display screen your logo, more underneath your product description, and these will been noticed by a lot of photonics industry experts.
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。
