These tables comprise only the most common host crystals; a lot of Many others exist, that happen to be significantly less routinely utilized.
These ions help the crystal to amplify mild in the laser wavelength by using stimulated emission, when energy is equipped on the crystal via absorption of pump gentle (�?optical pumping
Laser crystals are optical crystals �?usually one crystals (monocrystalline optical supplies) �?which happen to be employed as attain media for sound-point out lasers. In most cases, They can be doped with possibly trivalent rare earth ions or changeover metal ions.
Also, some versatility is missing in experiments if a single cannot Check out absorbers with distinctive thickness or doping concentration, such as, with no exchanging the laser crystal itself.
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。
Obviously, it is vitally fascinating that a offered crystal quality is generated constantly, Whilst diverse laser designs may have a different sensitivity to substance 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。
The host crystal is considerably more than simply a means to fix the laser-active ions at specific get more info positions in Room. Quite a few Houses with the host substance are very important:
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。
最近搜索： 大家在搜�?人工智能 图像处理 光子 热门搜索�?机器视觉 光通信 光纤传感器
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。
The medium ought to have a large transparency (small absorption and scattering) while in the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the caliber of the fabric, based on specifics with the fabrication procedure.
There is certainly a wide array of crystalline media, which may be grouped according to special atomic constituents and crystalline structures. Some crucial teams of crystals are:
