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。
Additionally, some versatility is shed in experiments if 1 can't Check out absorbers with unique thickness or doping concentration, such as, with no exchanging the laser crystal by itself.
This is a snap to carry out: just find the lock icon before the URL within the address bar and drag that to the bookmark toolbar With all the mouse. In the event you locate the bookmark entry also prolonged, you are able to correct-click on it to edit the text, e.g. applying "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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The maximum attainable doping focus can count strongly to the host material and its fabrication approach.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
For quasi-a few-amount laser gain media and even 3-stage get media, one frequently has to limit the size more info to a price that's far too shorter for efficient pump absorption, as reabsorption effects would otherwise spoil the overall performance. For side pumping, additional concerns come into play; besides efficient pump absorption, it's important to obtain a suitable spatial shape with the achieve profile.
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 formulated the globe’s major 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 incredibly huge emission spectra drives the event of laser diode pumped ultrafast reliable-condition lasers. With the increase in pulse Vitality, peak ability, and repetition amount of strong-condition lasers, laser crystals will produce in the direction of more substantial sizes, larger crystal top quality, and controllable essential effectiveness.
It could be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It may be mounted in certain good mount which also acts for a heat sink. More substantial crystals are often useful for facet pumping e.g. with high-ability diode bars.
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。
