激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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 carry out: just locate the lock icon before the URL within the address bar and drag that on the bookmark toolbar Using the mouse. Just in case you discover the bookmark entry as well very long, you may proper-simply click it to edit the textual content, e.g. using "RP Enc" as opposed to "RP Photonics Encyclopedia".

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。
g. a skinny disk. As A further illustration, Q-switched lasers achieve the next populace density in the higher laser amount and therefore are consequently additional sensitive to quenching outcomes and energy transfer processes; thus, a lessen doping density is usually appropriate for these products. For top-electrical power lasers, lessen doping densities are frequently accustomed to limit the density of heat generation, While thin-disk lasers function greatest with highly doped crystals. Several laser products and solutions don't reach the comprehensive overall performance prospective due to the fact these kinds of facts have not been properly labored out.
Laser modeling and simulation can be employed to reliably ascertain the ideal crystal dimensions, doping density And maybe values of further parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-three-amount laser attain media or simply a few-degree obtain media, one particular usually has to Restrict the size to a value which happens to be far too quick for efficient pump absorption, as reabsorption consequences would in any other case spoil the general performance. For facet pumping, supplemental click here issues come into Enjoy; Apart from efficient pump absorption, it is crucial to obtain an appropriate spatial condition in the get 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 made the whole world’s premier 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 incredibly huge emission spectra drives the development of laser diode pumped ultrafast solid-state lasers. With the rise in pulse Power, peak electrical power, and repetition fee of sound-condition lasers, laser crystals will establish in the direction of larger sized dimensions, greater crystal top quality, and controllable key overall performance.
With That idea, a person will not have to have a further saturable absorber crystal, to make sure that 1 may make extra compact Q-switched laser setups with decreased interior parasitic losses. Nonetheless, unwelcome Unwanted effects could also occur, including acquiring undesired valence states with the involved ions or Vitality transfers.
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。
