The most typical laser-Energetic scarce earth ions and host media along with some typical emission wavelengths are revealed in the next desk:
These ions help the crystal to amplify light on the laser wavelength by way of stimulated emission, when Strength is supplied towards the crystal through absorption of pump gentle (�?optical pumping
Laser crystals are optical crystals �?generally single crystals (monocrystalline optical products) �?that happen to be used as acquire media for stable-point out lasers. Typically, These are doped with possibly trivalent uncommon earth ions or changeover steel 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：
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。
Needless to say, it is very fascinating that a given crystal excellent is created consistently, Even though different laser patterns may have a different sensitivity to materials parameters.
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 elements have been shown in which some saturable absorber materials is included for passive Q switching of a laser.

Different crystalline products are quite distinctive relating to their hardness together with other Houses, which ascertain with which strategies and how effortlessly they may be Reduce and polished with good quality.
The medium must have a higher transparency (lower absorption and scattering) within the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this is dependent upon the quality of the material, based on specifics of the fabrication course of action.
It might be oriented for around perpendicular incidence of the laser beam, or at Brewster's angle. It can be preset in certain good mount which also functions as a warmth sink. Larger sized crystals usually are utilized for facet pumping e.g. with superior-electrical power diode bars.
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。
