These tables include only the most common host crystals; quite a few others exist, that are less routinely applied.
Listed here you'll be able to post questions and opinions. In terms of they get accepted via the author, they may appear above this paragraph together with the creator’s remedy. The creator will decide on acceptance according to specific standards. In essence, The problem has to be of sufficiently wide fascination.
Laser crystals are optical crystals �?generally one crystals (monocrystalline optical products) �?which happen to be applied as get media for good-condition lasers. Usually, they are doped with possibly trivalent scarce earth ions or changeover metal ions.
Also, some versatility is missing in experiments if a single can not Check out absorbers with unique thickness or doping concentration, such as, with no exchanging the laser crystal alone.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the higher-state 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。
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。
g. a skinny disk. As A different instance, Q-switched lasers attain the next inhabitants density while in the upper laser amount and they are for that reason a lot more delicate to quenching outcomes and Vitality transfer processes; thus, a lessen doping density is commonly appropriate for these devices. For top-electric power lasers, reduce doping densities will often be accustomed to Restrict the density of heat era, Even though slim-disk lasers get the job done very best with remarkably doped crystals. Quite a few laser products will not get to the comprehensive effectiveness potential simply because these aspects haven't been adequately labored out.
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。
It is obvious that various purposes produce extremely different necessities on laser attain media. Because of this, a wide vary of different crystals are applied, and generating the correct preference is important for constructing lasers with the best possible overall performance.

For numerous good reasons, composite crystals have gotten common. These Have a very spatially varying chemical composition and will be created with Distinctive designs.
Making use of our promoting offer, you'll be able to Display screen your brand, more underneath your merchandise description, and these will get more info been witnessed by many photonics gurus.
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。
