As far as they get accepted by the creator, they will surface higher than this paragraph together with the writer’s answer. The author will settle on acceptance based upon particular criteria. Primarily, the issue need to be of sufficiently broad desire.
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。
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：
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。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
The most attainable doping concentration can count strongly about the host materials and its fabrication method.
A couple of laser crystal materials are already shown exactly where some saturable absorber content is included 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 different apps lead to really distinct necessities on laser gain media. For that reason, a broad selection of various crystals are applied, and making the correct decision is important for setting up lasers with ideal functionality.

GWU-Lasertechnik has more than 30 a long time of practical experience in distributing laser crystals. Choose GWU to gain from our wide information and in-discipline practical experience!
It may be oriented for around perpendicular incidence on the more info laser beam, or at Brewster's angle. It might be fastened in a few stable mount which also functions as a heat sink. Greater crystals are frequently employed for aspect pumping e.g. with substantial-electric power diode bars.
