Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical elements) �?which happen to be made use of as achieve media for reliable-state lasers. In most cases, They are really doped with both trivalent scarce earth ions or transition metallic ions.
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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
GWU offers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a wide variety of technical specs. Apart from the very well-founded materials, progressive crystals with exceptional Qualities like Yb:CALGO can open new horizons for demanding laser applications. Regardless of no matter if specific pieces for R & D purposes are required or Price tag-economical figures in little, medium or large batches with in-time supply for your output line are desired: GWU’s committed provider helps to discover the ideal core parts for your software.
A significant area top quality is needless to say critical. Technical specs of surface area flatness here are often much better than . This can help to stop both equally scattering losses and wavefront distortions which could degrade the laser's beam quality. Additionally, scratch and dig technical specs
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Several laser crystal materials are already demonstrated exactly where some saturable absorber product is included for passive Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
All those surfaces which happen to be passed through the laser beam are Typically both oriented at Brewster's angle or have an anti-reflection coating.

The medium should have a substantial transparency (low absorption and scattering) inside the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, based on specifics in the fabrication course of action.
You can find an array of crystalline media, that may be grouped according to big atomic constituents and crystalline buildings. Some significant groups of crystals are:
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
