The most common laser-active uncommon earth ions and host media together with some common emission wavelengths are proven in the subsequent table:

These ions empower the crystal to amplify light in the laser wavelength via stimulated emission, when Electricity is supplied on the crystal by using absorption of pump light (�?optical pumping

激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。

A high floor good quality is certainly important. Specs of surface area flatness are sometimes a lot better than . This aids to stop both of those scattering losses and wavefront distortions which can degrade the laser's beam top quality. Moreover, scratch and dig specs

The utmost feasible doping focus can depend strongly about the host product and its fabrication process.

The host crystal is much more than just a method to repair the laser-Lively ions at particular positions in Place. A number of Homes of your host product are essential:

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。

Those people surfaces which might be passed because of the laser beam here are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

Diverse crystalline materials are quite different concerning their hardness and other Homes, which identify with which techniques And the way quickly they may be cut and polished with good quality.

The medium should have a significant transparency (reduced absorption and scattering) during the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the standard of the fabric, determined by information of your fabrication method.

It could be oriented for near perpendicular incidence in the laser beam, or at Brewster's angle. It may be set in some solid mount which also functions for a warmth sink. Greater crystals are generally used for facet pumping e.g. with significant-electric power diode bars.

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。
