These tables incorporate only the commonest host crystals; several Other people exist, which happen to be less commonly utilized.
These ions enable the crystal to amplify mild within the laser wavelength by means of stimulated emission, when Vitality is equipped to your crystal by way of absorption of pump light-weight (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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 a snap to perform: just locate the lock icon in front of the URL while in the handle bar and drag that for the bookmark toolbar While using the mouse. In case you discover the bookmark entry far too long, you'll be able to suitable-simply click it to edit the textual content, e.g. using "RP Enc" as an alternative to "RP Photonics Encyclopedia".
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。
g. a thin disk. As A further instance, Q-switched lasers access a higher populace density in the upper laser degree and so are therefore much more sensitive to quenching outcomes and Electrical power transfer procedures; consequently, a lessen doping density is often appropriate for these gadgets. For prime-electricity lasers, decrease doping densities will often be utilized to limit the density of warmth technology, While slim-disk lasers get the job done finest with remarkably doped crystals. A lot of laser merchandise usually do not reach the complete efficiency possible because these types of information have not been adequately worked out.
Laser modeling and simulation can be utilized to reliably determine the ideal crystal Proportions, doping density and possibly values of more parameters.

For quasi-a few-degree laser gain media or simply 3-stage acquire media, a person generally get more info must Restrict the duration to a value which happens to be also shorter for effective pump absorption, as reabsorption outcomes would normally spoil the overall performance. For aspect pumping, more concerns arrive into Enjoy; Other than efficient pump absorption, it is necessary to obtain an acceptable spatial form with the obtain 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。
