Laser modeling and simulation can be used to reliably establish the optimum crystal dimensions, doping density and possibly values of more 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 changeover cross-sections of pump and laser transitions and also the upper-condition 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。

For quasi-three-stage laser achieve media as well as three-amount attain media, just one usually ought to limit the duration to a value which is too small for successful pump absorption, as reabsorption results would or else spoil the overall performance. For aspect pumping, extra criteria arrive into Participate in; Aside from efficient pump absorption, it can be crucial to obtain an acceptable spatial shape of your acquire profile.

GWU-Lasertechnik has a lot more than thirty many years of expertise in distributing laser crystals. Opt for GWU to take pleasure in our huge information As well as in-industry practical experience!

A high damage threshold with regards to pulse fluence or peak depth can be important for prime-Electrical power amplifiers.

These ions allow the crystal to amplify light-weight for the laser wavelength by using stimulated emission, when energy is supplied on the crystal via absorption of pump mild (�?optical pumping

It might be oriented for in the vicinity of perpendicular incidence on the laser beam, or at Brewster's angle. It can be fixed in certain good mount which also acts for a heat sink. Larger sized crystals tend to be utilized for facet pumping e.g. with large-ability diode bars.

Below you could post concerns and responses. So far as they get acknowledged through the author, they will surface earlier mentioned this paragraph together with the author’s respond to. The writer will settle on acceptance according to selected requirements. Basically, the issue needs to be of sufficiently wide curiosity.

Individuals surfaces that are handed with the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

Of course, it's very attractive that a provided crystal top quality is created constantly, Though distinct laser styles can have another sensitivity to product parameters.

There may be here a wide array of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline buildings. Some critical groups of crystals are:

It is clear that different applications lead to very different requirements on laser achieve media. For that reason, a broad variety of different crystals are made use of, and building the best decision is essential for setting up lasers with optimum functionality.

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。
