Here you'll be able to submit inquiries and responses. So far as they get recognized because of the author, they may surface over this paragraph along with the writer’s remedy. The author will settle on acceptance dependant on certain conditions. Primarily, the issue should be of sufficiently wide fascination.

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 not hard to perform: just discover the lock icon in front of the URL from the handle bar and drag that to the bookmark toolbar Together with the mouse. In the event you discover the bookmark entry far too extensive, you can right-simply click it to edit the textual content, e.g. working with "RP Enc" in lieu 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。

A large floor high-quality is obviously critical. Requirements of floor flatness are often better than . This helps to prevent both scattering losses and wavefront distortions which can degrade the laser's beam quality. In addition, scratch and dig technical specs

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 of laser crystal products are actually demonstrated in which 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 apparent that diverse programs cause incredibly unique prerequisites on laser gain media. For this reason, a wide array of various crystals are employed, and producing the correct option is important for setting up lasers with optimum overall performance.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

In 2017, we developed the earth’s largest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with exceptionally vast emission spectra drives the event of laser diode pumped ultrafast solid-condition lasers. With the rise in pulse Power, peak electric power, and repetition get more info level of strong-state lasers, laser crystals will build in direction of much larger dimensions, bigger crystal high quality, and controllable crucial effectiveness.

There's an array of crystalline media, which may be grouped according to big atomic constituents and crystalline buildings. Some important groups of crystals are:

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
