The most common laser-Energetic exceptional earth ions and host media together with some standard emission wavelengths are proven in the following desk:

These ions allow the crystal to amplify light within the laser wavelength by means of stimulated emission, when Electricity is supplied to the crystal via absorption of pump gentle (�?optical pumping

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

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 a snap to complete: just discover the lock icon before the URL inside the tackle bar and drag that to the bookmark toolbar Along with the mouse. In case you discover the bookmark entry too extensive, you can right-simply click 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。

Obviously, it is very fascinating that a provided crystal high quality is produced continually, Though different laser models can have a unique sensitivity to material parameters.

The utmost doable doping concentration can depend strongly to the host substance and its fabrication technique.

The host crystal is much more than simply a means to fix the laser-active ions at specific positions in Room. Many properties from the host materials are essential:

For quasi-a few-degree laser attain media and even a few-level get media, 1 generally must limit the duration to a value and that is too limited for economical pump absorption, as reabsorption effects would in any other case spoil the efficiency. For aspect pumping, more considerations come into Perform; Aside from productive pump absorption, it can be crucial to acquire an acceptable spatial condition with the get profile.

For several good click here reasons, composite crystals have gotten well-known. These have a spatially different chemical composition and might be created with special shapes.

There may be a variety of crystalline media, which can be grouped according to big atomic constituents and crystalline structures. Some crucial groups of crystals are:
