The most common laser-Lively scarce earth ions and host media together with some regular emission wavelengths are proven in the subsequent table:
These ions help the crystal to amplify mild for the laser wavelength through stimulated emission, when Electrical power is provided to the crystal by using absorption of pump gentle (�?optical pumping
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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。
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。
Not surprisingly, it is extremely appealing that a specified crystal top quality is manufactured constantly, While different laser patterns may have another sensitivity to material parameters.
The maximum doable doping concentration can rely strongly to the host product and its fabrication method.
The host crystal is a great deal more than just a means to repair the laser-Lively ions at selected positions in Place. Quite a few Attributes of your host content are important:
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�?制造能力
It is obvious that diverse purposes lead to incredibly various requirements on laser attain media. This is why, a broad assortment of different crystals are utilised, and generating the appropriate decision is essential for setting up lasers with the best possible efficiency.
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。
For several motives, composite crystals are becoming common. These Use a spatially different chemical composition and will be built more info with Distinctive designs.
Working with our marketing bundle, you can Show your emblem, even further below your item description, and these will been witnessed by quite a few photonics gurus.
