The creator will make a decision on acceptance dependant on selected standards. In essence, the issue must be of adequately wide curiosity.
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。
Which geometry, dopant and doping focus from the get medium are most beneficial rely on various things. The readily available pump source (kind of laser diode or lamp) as well as the envisaged pumping arrangement are very important aspects, but the fabric alone also has some affect. As an example, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with reasonably tiny pump and laser beam diameter, is much more ideal than e.
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 extremely desirable that a given crystal high-quality is manufactured continually, Despite the fact that distinct laser styles might have a distinct sensitivity to material parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A handful click here of laser crystal elements have already been shown exactly where some saturable absorber product is incorporated for passive Q switching of a laser.
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。
It is apparent that distinctive programs lead to extremely distinct necessities on laser get media. Due to this, a wide vary of various crystals are applied, and building the best option is important for setting up lasers with the best possible general performance.

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 strong-condition lasers. With the rise in pulse Electrical power, peak power, and repetition charge of sound-condition lasers, laser crystals will establish towards more substantial sizes, better crystal high quality, and controllable important efficiency.
There is certainly an array of crystalline media, which can be grouped according to special atomic constituents and crystalline buildings. Some vital teams of crystals are:
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。
