Laser Crystal - An Overview

Various crystalline resources are really various concerning their hardness together with other Attributes, which determine with which methods and how conveniently they may be Slice and polished with high quality.
The medium must have a higher transparency (low absorption and scattering) inside the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this will depend on the caliber of the fabric, determined by details on the fabrication method.
The host crystal is considerably more than just a way to repair the laser-active ions at sure positions in Room. Many Homes with the host materials are essential:
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。
For quasi-3-stage laser achieve media or maybe 3-stage achieve media, just one generally ought to limit the length to a worth that is as well short for efficient pump absorption, as reabsorption consequences would usually spoil the effectiveness. For side pumping, supplemental issues come into Perform; Other than productive pump absorption, it is important to get an acceptable spatial condition on the gain profile.

A high problems threshold in terms of pulse fluence or peak depth could be vital for high-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：

These tables include only the commonest host crystals; several Other people exist, which are much less routinely employed.
The commonest laser-active unusual earth ions and host media along with some typical emission wavelengths are proven in the subsequent desk:
A number of laser crystal resources are already demonstrated where by some saturable absorber substance is incorporated for passive Q switching of the laser.
For different reasons, composite crystals have become well-liked. These Have got a spatially varying chemical composition and might be created with Particular designs.
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。
With that concept, 1 doesn't need to have a further saturable absorber crystal, making sure that a person may perhaps make more compact Q-switched laser setups with lower interior parasitic losses. Nevertheless, unwanted Unwanted effects may additionally manifest, for instance getting undesirable valence states on the involved ions or Electrical power transfers.

Laser crystals are optical crystals �?ordinarily solitary crystals (monocrystalline optical elements) �?which might be utilised as obtain media for solid-condition lasers. Generally, They are really doped with both trivalent scarce earth ions or transition steel ions.
