Laser Crystal for Dummies

Blog Article

These tables incorporate only the commonest host crystals; numerous Some others exist, that are a lot less frequently utilized.

Below you can submit concerns and remarks. So far as they get recognized by the author, they'll appear over this paragraph together with the creator’s respond to. The writer will choose acceptance determined by specified requirements. Basically, The difficulty must be of adequately broad interest.

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

Also, some adaptability is lost in experiments if a single are unable to Check out absorbers with unique thickness or doping concentration, by way of example, devoid of exchanging the laser crystal alone.

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

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 large floor high-quality is obviously crucial. Specifications of surface area flatness are sometimes a lot better than . This will help to stop both equally scattering losses and wavefront distortions that may degrade the laser's beam high-quality. On top of that, scratch and dig technical specs

The utmost possible doping concentration can count strongly within read more the host product and its fabrication approach.

The host crystal is much more than just a way to repair the laser-Lively ions at certain positions in space. Quite a few Homes on the host product are important:

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

These surfaces which are handed from the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.

For various explanations, composite crystals have become well-liked. These have a spatially different chemical composition and may be made with Distinctive designs.

There is certainly a wide array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline constructions. Some essential groups 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。
