Listed here you'll be able to post concerns and opinions. In terms of they get acknowledged with the creator, they may appear previously mentioned this paragraph together with the creator’s reply. The writer will choose acceptance based on certain conditions. In essence, The difficulty should be of adequately wide fascination.

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical components) �?which happen to be utilised as gain media for strong-condition lasers. Generally, they are doped with both trivalent scarce earth ions or transition steel ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping concentration from the obtain medium are most useful depend on various things. The out there pump source (variety of laser diode or lamp) and the envisaged pumping arrangement are crucial aspects, but the fabric alone also has some impact. For example, titanium–sapphire lasers ought to be pumped with large intensities, for which the shape of the transversely cooled rod, operated with fairly small pump and laser beam diameter, is much more proper than e.

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 higher floor good quality is certainly important. Specifications of surface area flatness tend to be a lot better than . This can help to stop the two scattering losses and wavefront distortions that may degrade the laser's beam quality. On top of that, scratch and dig specs

g. a skinny disk. As another case in point, Q-switched lasers attain a higher population density inside the upper laser stage and so are therefore additional sensitive to quenching effects and energy transfer processes; therefore, a reduced doping density is often appropriate for these equipment. For prime-electrical power lasers, reduce doping densities tend to be used to Restrict the density of heat generation, While skinny-disk lasers perform greatest with remarkably doped crystals. Several laser products don't get to the complete general performance prospective since these kinds of particulars haven't been thoroughly labored out.

Laser modeling and simulation can be utilized to reliably determine the optimum crystal Proportions, doping density and possibly values of added parameters.

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。

Different crystalline elements are incredibly distinct regarding their hardness and other Qualities, which establish with which strategies And the way quickly they may be Slice and polished with good quality.

For different motives, composite crystals are becoming well-liked. These read more have a spatially varying chemical composition and can be created with Specific styles.

There exists a wide range of crystalline media, that may be grouped according to big atomic constituents and crystalline structures. Some critical teams of crystals are:

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。
