Different crystalline supplies are quite different about their hardness along with other Homes, which decide with which approaches and how easily they may be Slice and polished with high 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 crystal is far more than simply a means to repair the laser-Energetic ions at specified positions in space. Several Attributes on the host material are essential:

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-a few-level laser acquire media as well as a few-degree achieve media, just one frequently should Restrict the length to a value that's far too shorter for effective pump absorption, as reabsorption consequences would in any other case spoil the general performance. For facet pumping, supplemental considerations come into play; Moreover effective pump absorption, it can be crucial to obtain an appropriate spatial condition of the obtain profile.

A superior hurt threshold when it comes to pulse fluence or peak intensity is often critical for top-Electrical power amplifiers.

These ions allow the crystal to amplify gentle within the laser wavelength through stimulated emission, when energy is provided to your crystal via absorption of pump gentle (�?optical pumping

It might be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It might be fastened in certain good mount which also functions for a warmth sink. Greater crystals are generally utilized for facet pumping e.g. with higher-energy diode bars.

The most typical laser-active scarce earth ions and host media along with some normal emission wavelengths are demonstrated in the next table:

All those surfaces more info which might be passed with the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

Not surprisingly, it is rather fascinating that a provided crystal excellent is manufactured persistently, Even though unique laser designs might have a distinct sensitivity to product parameters.

There exists a wide array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some vital groups of crystals are:

GWU presents all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) with a wide selection of technical specs. Besides the well-recognized products, progressive crystals with excellent Houses like Yb:CALGO can open new horizons for demanding laser apps. Irrespective of regardless of whether person parts for R & D needs are needed or Price-effective figures in compact, medium or massive batches with in-time supply to the creation line are needed: GWU’s focused provider helps to locate the most effective Main parts on your application.

Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical components) �?which are utilized as acquire media for solid-condition lasers. Usually, They're doped with either trivalent unusual earth ions or transition 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。
