Here you'll be able to post issues and reviews. As far as they get accepted by the writer, they're going to appear above this paragraph together with the writer’s reply. The creator will choose acceptance depending on particular standards. Essentially, The difficulty have to be of adequately wide 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（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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the upper-condition life span.

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。

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。

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。

Laser modeling and simulation can be utilized to reliably ascertain the optimum crystal dimensions, doping density And perhaps values of additional parameters.

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-three-degree laser gain media or maybe three-degree get media, a single normally has to Restrict the duration to a value that's much too quick for successful pump absorption, as reabsorption consequences would normally spoil the performance. For side pumping, added criteria occur into play; Apart from productive pump absorption, it is crucial to acquire an acceptable spatial form on the achieve profile.

Diverse crystalline elements are very different relating to their hardness and also other Homes, which establish with which techniques And the way quickly they are often Lower and polished with website high quality.

GWU-Lasertechnik has over thirty decades of expertise in distributing laser crystals. Pick GWU to get pleasure from our extensive expertise and in-field experience!

There may be a variety of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline constructions. Some crucial groups of crystals are:
