Laser modeling and simulation may be used to reliably decide the optimum crystal Proportions, doping density and possibly values of supplemental 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 crystal is much more than simply a means to repair the laser-Energetic ions at particular positions in space. A number of Homes of your host product are important:

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 feasible doping concentration can count strongly to the host substance and its fabrication strategy.

g. a thin disk. As another example, Q-switched lasers reach a greater population density during the higher laser stage and they are as a result much more delicate to quenching outcomes and Vitality transfer processes; consequently, a lower doping density is frequently appropriate for these products. For high-electric power lasers, lower doping densities are sometimes utilized to Restrict the density of heat era, While skinny-disk lasers do the job ideal with remarkably doped crystals. Many laser merchandise do not get to the whole effectiveness probable simply because these types of specifics have not been thoroughly labored out.

GWU-Lasertechnik has greater than 30 years of encounter in distributing laser crystals. Select GWU to take advantage of our huge information As well as in-discipline encounter!

A superior hurt threshold in terms of pulse fluence or peak depth may be important for high-Electrical power amplifiers.

These ions empower the crystal to amplify light with the laser wavelength through stimulated emission, when energy is provided towards the crystal via absorption of pump light-weight (�?optical pumping

Which geometry, dopant and doping concentration with the attain medium are most beneficial count on many factors. The out there pump source (kind of laser diode or lamp) plus the envisaged pumping arrangement are important elements, but the fabric by itself also has some affect. As an example, titanium–sapphire lasers need to be pumped with large intensities, for which the form of a transversely cooled rod, operated with fairly modest pump and laser beam diameter, is much more ideal than e.

These tables check here contain only the commonest host crystals; several Some others exist, which might be a lot less often used.

The most typical laser-Lively rare earth ions and host media together with some common emission wavelengths are demonstrated in the following desk:

All those surfaces that are handed from the laser beam are Ordinarily either oriented at Brewster's angle or have an anti-reflection coating.

Of course, it is rather fascinating that a given crystal top quality is developed continuously, Even though distinct laser models might have a unique sensitivity to content parameters.

You can find a variety of crystalline media, which can be grouped according to special atomic constituents and crystalline constructions. Some significant teams 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 �?usually solitary crystals (monocrystalline optical products) �?which can be made use of as acquire media for reliable-point out lasers. Generally, They can be doped with possibly trivalent rare earth ions or transition steel 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。
