Various crystalline products are certainly various relating to their hardness and also other properties, which establish with which solutions and how quickly they may be cut and polished with good quality.

The medium must have a high transparency (minimal absorption and scattering) from the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the quality of the material, based on aspects from the fabrication course of action.

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the upper-state lifetime.

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-three-level laser attain media or simply 3-degree acquire media, one normally ought to limit the length to a worth and that is way too quick for productive pump absorption, as reabsorption consequences would normally spoil the efficiency. For side pumping, more factors come into Enjoy; Apart from economical pump absorption, it is crucial to obtain an acceptable spatial shape with the obtain profile.

g. a thin disk. As A further instance, Q-switched lasers arrive at a greater inhabitants density within the higher laser amount and therefore are thus more sensitive to quenching outcomes and Power transfer processes; thus, a reduce doping density is usually suitable for these equipment. For high-electrical power lasers, decreased doping densities are often utilized to Restrict the density of heat generation, Despite the fact that slender-disk lasers work very best with very doped crystals. Quite a few laser products and solutions don't reach the total functionality probable for the reason that this kind of aspects haven't been thoroughly labored out.

GWU-Lasertechnik has in excess of 30 many years of encounter in distributing laser crystals. Choose GWU to benefit from our vast knowledge As well as in-discipline knowledge!

Also, some versatility is lost in experiments if just one can not Check out absorbers with diverse thickness or doping concentration, by way of example, with out exchanging the laser crystal alone.

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 focus from the get medium are most advantageous rely on various factors. The offered pump resource (type of laser diode or lamp) as well as the envisaged pumping arrangement are very important factors, but the material itself also has some affect. One example is, titanium–sapphire lasers ought to be pumped with large intensities, for which the form of the transversely cooled rod, operated with rather little pump and laser beam diameter, is much more acceptable than e.

It could be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It can be fixed in some sound mount which also acts like a heat sink. More substantial crystals usually are employed for facet pumping e.g. with significant-ability diode bars.

The commonest laser-Energetic unusual earth ions and host media together with some common emission wavelengths are shown in the subsequent desk:

A handful of laser crystal components have been demonstrated where by some saturable absorber materials is incorporated for passive Q more info switching of the laser.

For different explanations, composite crystals have become well known. These have a spatially various chemical composition and will be produced with Exclusive styles.

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 will not need to have a further saturable absorber crystal, making sure that just one may perhaps make extra compact Q-switched laser setups with lessen interior parasitic losses. Having said that, unwelcome side effects may also occur, which include getting undesired valence states with the involved ions or Electrical power transfers.

GWU provides all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) that has a broad number of technical specs. Moreover the effectively-established products, modern crystals with exceptional Attributes like Yb:CALGO can open up new horizons for demanding laser applications. It does not matter no matter whether person parts for R & D reasons are required or Price tag-productive numbers in modest, medium or large batches with in-time shipping for the creation line are needed: GWU’s devoted company helps to discover the best core parts for your application.

Laser crystals are optical crystals �?typically single crystals (monocrystalline optical elements) �?which are utilised as attain media for strong-condition lasers. Typically, they are doped with either trivalent unusual earth ions or changeover metallic ions.
