蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光镜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 �?generally single crystals (monocrystalline optical supplies) �?which happen to be used as attain media for good-point out lasers. In most cases, They are really doped with either trivalent scarce earth ions or transition metallic ions.

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the upper-condition lifetime.
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 An additional illustration, Q-switched lasers achieve the next inhabitants density from the higher laser stage and therefore are therefore a lot more sensitive to quenching results and Electricity transfer procedures; as a result, a lower doping density is commonly suitable for these products. For prime-electrical power lasers, lower doping densities will often be utilized to limit the density of warmth generation, Whilst slim-disk lasers operate greatest with really doped crystals. A lot of laser merchandise will not reach the whole performance prospective because this kind of information haven't been thoroughly 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。
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-a few-stage laser gain media or simply a few-amount read more get media, one particular normally ought to limit the length to a worth which can be also quick for productive pump absorption, as reabsorption results would otherwise spoil the overall performance. For facet pumping, supplemental considerations occur into Engage in; Apart from efficient pump absorption, it is crucial to get a suitable spatial form with the obtain profile.
Distinct crystalline elements are very various about their hardness and various Homes, which decide with which techniques And just how easily they may be Minimize and polished with top quality.
GWU-Lasertechnik has a lot more than 30 several years of expertise in distributing laser crystals. Pick GWU to take advantage of our broad awareness and in-industry knowledge!
It could be oriented for in close proximity to perpendicular incidence on the laser beam, or at Brewster's angle. It may be fastened in some good mount which also functions like a warmth sink. Bigger crystals are frequently used for side pumping e.g. with substantial-power diode bars.
