Various crystalline supplies are certainly distinctive relating to their hardness and various Qualities, which ascertain with which approaches And just how easily they are often Reduce and polished with high quality.
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 a lot more than simply a method to repair the laser-active ions at certain positions in Room. Several Attributes with the host substance are crucial:
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 utmost possible doping concentration can depend strongly about the host product and its fabrication strategy.
g. a thin disk. As A different case in point, Q-switched lasers arrive at the next population density in the upper laser level and they are hence far more delicate to quenching effects and energy transfer procedures; as a result, a lessen doping density is usually appropriate for these units. For high-electric power lasers, reduced doping densities tend to be accustomed to Restrict the density of warmth era, Whilst thin-disk lasers get the job done greatest with very doped crystals. Numerous laser solutions do not reach the complete general performance opportunity simply because these particulars have not been adequately labored out.
GWU-Lasertechnik has a lot more than 30 years of expertise in distributing laser crystals. Opt for GWU to reap the benefits of our vast know-how As well as in-discipline experience!
Moreover, some versatility is dropped in experiments if one particular can not try out absorbers with distinctive thickness or doping concentration, as an example, without having exchanging the laser crystal alone.
These ions enable the crystal to amplify light-weight on the laser wavelength by using stimulated emission, when Vitality is provided towards the crystal through absorption of pump gentle (�?optical pumping

These tables include only the commonest host crystals; several Other individuals exist, that are a Laser Crystal lot less often applied.
The most common laser-active scarce earth ions and host media together with some normal emission wavelengths are revealed in the following desk:
A handful of laser crystal products have been demonstrated in which some saturable absorber product is incorporated for passive Q switching of the laser.
Not surprisingly, it's very desirable that a supplied crystal high quality is created continuously, Despite the fact that unique laser layouts might have a special sensitivity to materials parameters.
There may be an array of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline constructions. Some essential teams of crystals are:
With That idea, 1 would not need to have an extra saturable absorber crystal, to make sure that just one might make additional compact Q-switched laser setups with reduce inner parasitic losses. However, undesirable Unwanted side effects may also take place, for instance getting unwelcome valence states from the concerned ions or Electricity transfers.

It is obvious that distinctive purposes result in quite different demands on laser attain media. Because of this, a broad assortment of different crystals are applied, and earning the proper selection is important for constructing lasers with optimum efficiency.
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。
