Distinctive crystalline elements are really various about their hardness and various Homes, which determine with which procedures and how quickly they can be Minimize and polished with good quality.

The medium must have a superior transparency (minimal absorption and scattering) during the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this will depend on the standard of the material, based on aspects of your fabrication approach.

The host crystal is a lot more than just a way to fix the laser-active ions at specific positions in Room. A variety of Houses with the host substance are crucial:

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。

The most achievable doping focus can rely strongly on the host content and its fabrication method.

A substantial damage threshold with regard to pulse fluence or peak intensity might be important for prime-Electrical power amplifiers.

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：

It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's click here angle. It can be fixed in some strong mount which also acts as being a heat sink. Bigger crystals are generally utilized for side pumping e.g. with higher-energy diode bars.

In this article it is possible to submit questions and opinions. So far as they get acknowledged by the creator, they are going to appear higher than this paragraph together with the author’s remedy. The writer will decide on acceptance based upon specific conditions. In essence, the issue need to be of sufficiently wide curiosity.

Those people surfaces that happen to be passed with the laser beam are Usually both oriented at Brewster's angle or have an anti-reflection coating.

For several reasons, composite crystals have become preferred. These Possess a spatially various chemical composition and will be produced with Specific styles.

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

It is obvious that distinct apps bring about incredibly different needs on laser achieve media. Because of this, a broad array of various crystals are used, and producing the appropriate option is important for setting up lasers with ideal 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。
