Unique crystalline elements are really unique regarding their hardness and also other Qualities, which identify with which approaches and how quickly they can be Slice and polished with good quality.

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 as well as the upper-state lifetime.

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-amount laser get media or maybe 3-level gain media, a person generally should limit the duration to a price which can be as well shorter for successful pump absorption, as reabsorption results would otherwise spoil the general performance. For aspect pumping, extra criteria arrive into play; Moreover effective pump absorption, it is important to get a suitable spatial form of the achieve profile.

By distributing the data, you give your consent towards the prospective publication of the inputs on our Web site As outlined by our rules. (Should you afterwards retract your consent, we will delete These inputs.) As your inputs are initial reviewed from the writer, They could be posted with a few delay.

GWU-Lasertechnik has a lot more than thirty decades of practical experience in distributing laser crystals. Opt for GWU to take advantage of our huge know-how As well as in-industry experience!

A high injury threshold regarding pulse fluence or peak intensity is often important for top-Electricity amplifiers.

These ions enable the crystal to amplify light-weight on the laser wavelength by way of stimulated click here emission, when Strength is supplied for the crystal by using absorption of pump gentle (�?optical pumping

Which geometry, dopant and doping focus of your gain medium are most advantageous depend on many variables. The out there pump supply (sort of laser diode or lamp) as well as the envisaged pumping arrangement are very important elements, but the material by itself also has some affect. One example is, titanium–sapphire lasers ought to be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with reasonably little pump and laser beam diameter, is much more proper than e.

These tables have only the commonest host crystals; quite a few Some others exist, which might be a lot less often utilized.

The most typical laser-active uncommon earth ions and host media along with some common emission wavelengths are revealed in the following table:

Individuals surfaces which can be passed because of the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.

Naturally, it is rather attractive that a specified crystal high-quality is generated continually, although various laser models may have a different sensitivity to materials parameters.

There may be a wide array of crystalline media, which can be grouped according to special atomic constituents and crystalline structures. Some important 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

It is obvious that distinctive applications bring about extremely distinct necessities on laser attain media. For this reason, a broad assortment of different crystals are utilised, and building the ideal choice is essential for constructing lasers with optimum efficiency.

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。
