These tables have only the most typical host crystals; many Other folks exist, that are a lot less routinely made use of.

These ions allow the crystal to amplify light at the laser wavelength by using stimulated emission, when Vitality is supplied on the crystal through absorption of pump light (�?optical pumping

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：

晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心

A substantial floor quality is needless to say important. Specs of surface flatness will often be a lot better than . This will help to avoid the two scattering losses and wavefront distortions which could degrade the laser's beam top quality. Furthermore, scratch and dig specifications

g. a skinny disk. As Yet another case in point, Q-switched lasers get to a higher inhabitants density during the upper laser level and so are therefore a lot more delicate to quenching consequences and Power transfer processes; thus, a lower doping density is usually appropriate for these products. For top-power lasers, reduce doping densities in many cases are utilized to limit the density of heat generation, Even though thin-disk lasers function greatest with very doped crystals. Several laser merchandise tend not to reach the complete functionality prospective since this kind of details haven't been thoroughly worked out.

The host crystal is far more than simply a method to fix the laser-active ions at selected positions in space. Quite a few Homes in the host substance are crucial:

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。

It is clear that distinctive programs bring about incredibly various requirements on laser acquire media. This is why, a wide array of read more various crystals are applied, and producing the correct decision is essential for developing lasers with ideal general performance.

Different crystalline materials are extremely different regarding their hardness and also other Qualities, which determine with which strategies And exactly how conveniently they are often Slash and polished with top quality.

The medium must have a large transparency (low absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the caliber of the fabric, determined by facts from the fabrication system.

It may be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It can be fastened in a few stable mount which also functions being a heat sink. Greater crystals are generally utilized for side pumping e.g. with superior-ability 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。
