Laser modeling and simulation may be used to reliably figure out the the best possible crystal dimensions, doping density And maybe values of further parameters.

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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the upper-point out life span.

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。

The most attainable doping focus can count strongly about the host product and its fabrication technique.

GWU-Lasertechnik has over 30 decades of practical experience in distributing laser crystals. Pick out GWU to take advantage of our vast understanding and in-field encounter!

A high injury threshold when it comes to pulse fluence or peak intensity may be important for top-Vitality amplifiers.

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：

Which geometry, dopant and doping focus on the gain medium are most beneficial depend on various components. The accessible pump resource (sort of laser diode or lamp) as well as envisaged pumping arrangement are very important things, but the material itself also has some influence. By way of example, titanium–sapphire lasers should be pumped with superior intensities, for which the shape of the transversely cooled rod, operated with relatively little pump and laser beam diameter, is much more suitable than e.

It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It can be preset in a few strong mount which also acts to be a heat sink. Larger sized crystals tend to be useful for facet pumping e.g. with significant-power diode click here bars.

The most typical laser-active exceptional earth ions and host media together with some usual emission wavelengths are demonstrated in the following table:

People surfaces which happen to be handed because of the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

Obviously, it is rather attractive that a given crystal top quality is generated consistently, Despite the fact that diverse laser types might have another sensitivity to material parameters.

There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some important groups of crystals are:

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

Laser crystals are optical crystals �?generally one crystals (monocrystalline optical components) �?which happen to be utilized as get media for solid-state lasers. Typically, they are doped with either trivalent unusual earth ions or changeover metallic ions.

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。
