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。
This is straightforward to carry out: just locate the lock icon in front of the URL while in the address bar and drag that for the bookmark toolbar While using the mouse. In case you find the bookmark entry also very long, you could correct-simply click it to edit the text, e.g. utilizing "RP Enc" as opposed to "RP Photonics Encyclopedia".
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。
Needless to say, it is rather appealing that a offered crystal quality is manufactured continually, Despite the fact that various laser designs may have a different sensitivity to substance parameters.
The most attainable doping focus can rely strongly over the host material and its fabrication system.
A few laser crystal resources happen to be get more info demonstrated the place some saturable absorber material is incorporated for passive Q switching of a laser.
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。
It is obvious that different applications cause pretty different specifications on laser get media. For this reason, a wide range of various crystals are applied, and building the best decision is essential for developing lasers with ideal efficiency.

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 development of Yb and Tm doped GdScO3 laser crystals with exceptionally wide emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the increase in pulse Electricity, peak energy, and repetition fee of stable-point out lasers, laser crystals will develop in direction of much larger dimensions, bigger crystal high quality, and controllable key overall performance.
There exists a variety of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some essential groups of crystals are:
