5 Simple Techniques For Laser Crystal

Blog Article

Laser modeling and simulation can be used to reliably decide the optimum crystal Proportions, 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 crystal is considerably more than simply a method to repair the laser-Lively ions at certain positions in Area. Several Homes in the host content are very important:

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 maximum doable doping focus can count strongly within the host content and its fabrication method.

Additionally, some flexibility is shed in experiments if one can not Check out absorbers with diverse thickness or doping concentration, by way of example, without exchanging the laser crystal itself.

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：

Which geometry, dopant and doping concentration of the get medium are most advantageous depend upon numerous factors. The offered pump supply (kind of laser diode or lamp) along with the envisaged pumping arrangement are important elements, but the material by itself also has some affect. One example is, titanium–sapphire lasers need to be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with fairly small pump and laser beam diameter, is a lot more suitable than e.

It may be oriented for close to perpendicular incidence of your laser beam, or at Brewster's get more info angle. It can be fastened in some stable mount which also acts being a warmth sink. Bigger crystals are frequently employed for aspect pumping e.g. with high-ability diode bars.

Listed here it is possible to post concerns and opinions. So far as they get acknowledged because of the writer, they'll seem previously mentioned this paragraph together with the creator’s answer. The author will determine acceptance according to particular conditions. Primarily, The difficulty must be of adequately broad interest.

Those surfaces which happen to be handed with the laser beam are Generally both oriented at Brewster's angle or have an anti-reflection coating.

Obviously, it's very desirable that a supplied crystal top quality is manufactured persistently, Though unique laser patterns might have a unique sensitivity to materials parameters.

There exists an array of crystalline media, which may be grouped according to big atomic constituents and crystalline constructions. Some vital teams of crystals are:

Laser crystals are optical crystals �?commonly one crystals (monocrystalline optical resources) �?that happen to be used as get media for strong-point out lasers. Usually, They may be doped with either trivalent rare earth ions or changeover 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。
