The Definitive Guide to Laser Crystal

The most typical laser-active uncommon earth ions and host media together with some normal emission wavelengths are proven in the following desk:

In this article you'll be able to post thoughts and comments. As far as they get approved via the author, they'll seem previously mentioned this paragraph together with the writer’s response. The writer will make a decision on acceptance dependant on certain criteria. Primarily, The problem have to be of adequately broad curiosity.

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。

This is straightforward to carry out: just find the lock icon in front of the URL from the handle bar and drag that for the bookmark toolbar Along with the mouse. Just in case you find the bookmark entry also very long, you can correct-click on it to edit the textual content, e.g. working with "RP Enc" instead of "RP Photonics Encyclopedia".

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

Needless to say, it's very desirable that a specified crystal high-quality is developed continually, While distinct laser designs may have a unique sensitivity to materials parameters.

The maximum possible doping concentration can depend strongly around the host material and its here fabrication approach.

The host crystal is far more than just a means to fix the laser-Lively ions at specific positions in Area. Several Houses in the host content are important:

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

All those surfaces which happen to be handed from the laser beam are Usually both oriented at Brewster's angle or have an anti-reflection coating.

Distinctive crystalline products are really distinct about their hardness and other Qualities, which identify with which strategies And the way very easily they may be Minimize and polished with high quality.

The medium ought to have a higher transparency (small absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the quality of the material, based on specifics of the fabrication procedure.

There exists an array of crystalline media, which can be grouped according to special atomic constituents and crystalline buildings. Some essential teams of crystals are:
