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。
This is simple to accomplish: just find the lock icon in front of the URL during the deal with bar and drag that into the bookmark toolbar With all the mouse. In the event you locate the bookmark entry too extended, you may ideal-click on it to edit the text, e.g. working with "RP Enc" instead of "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。
Certainly, it is very desirable that a specified crystal good quality is made regularly, Even though different laser designs might have a distinct sensitivity to content 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。
Some laser crystal components have been demonstrated wherever some saturable absorber material is integrated 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 clear that unique purposes lead to extremely distinct necessities on laser get media. Because of this, a wide array of various crystals are applied, and building the ideal preference is important for setting up lasers with optimum overall performance.

In 2017, we developed the globe’s largest 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 vast emission spectra drives the event of laser diode pumped ultrafast good-point out lasers. With the increase in pulse Electrical power, peak electricity, and repetition rate of strong-state lasers, laser crystals will produce toward larger sized dimensions, higher crystal high quality, Laser Crystal and controllable crucial functionality.
There may be a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some important groups 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。
