These tables contain only the commonest host crystals; several Other folks exist, which might be a lot less commonly applied.
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。
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical supplies) �?which are utilised as attain media for reliable-state lasers. Usually, they are doped with either trivalent scarce earth ions or transition metallic ions.
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 easy to try and do: just discover the lock icon in front of the URL inside the deal with bar and drag that for the bookmark toolbar While using the mouse. In the event you discover the bookmark entry too long, it is possible to ideal-simply click it to edit the text, e.g. using "RP Enc" instead of "RP Photonics Encyclopedia".
GWU offers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a wide a number of specifications. Moreover the well-founded materials, innovative crystals with fantastic properties like Yb:CALGO can open up new horizons for demanding laser apps. It does not matter whether person parts for R & D needs are necessary or cost-successful figures in little, medium or substantial batches with in-time shipping and delivery with the manufacturing line are desired: GWU’s devoted assistance helps to discover the finest Main elements in your application.
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 One more case in point, Q-switched lasers achieve the next populace density during the upper laser stage and they are as a result extra sensitive to quenching results and Electricity transfer processes; as a result, a decreased doping density is frequently suitable for these devices. For high-energy lasers, reduced doping densities are frequently accustomed to limit the density of warmth technology, Whilst slender-disk lasers do the job most effective with remarkably doped crystals. Quite a few laser solutions tend not to reach the full performance opportunity for the reason that these specifics haven't been appropriately worked out.
Laser modeling and simulation can be employed to reliably identify the ideal crystal Proportions, doping density and possibly values of supplemental parameters.
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-3-level laser gain media or simply 3-level attain media, just one typically needs to Restrict the length to a price that is as well brief for successful pump absorption, as reabsorption effects would usually check here spoil the overall performance. For facet pumping, further criteria come into Engage in; Other than efficient pump absorption, it is crucial to acquire an acceptable spatial condition of the obtain profile.
