Distinct crystalline materials are certainly diverse about their hardness together with other Qualities, which ascertain with which techniques And just how easily they are often Slice and polished with good quality.
The medium must have a high transparency (lower absorption and scattering) in the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this depends upon the caliber of the fabric, based on details in the fabrication system.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the higher-condition 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。
The maximum doable doping concentration can rely strongly over the host product and its fabrication technique.
g. a thin disk. As A further illustration, Q-switched lasers access an increased populace density in the upper laser stage and therefore are hence more delicate to quenching effects and energy transfer processes; hence, a lower doping density is usually suitable for these products. For prime-electrical power lasers, reduce doping densities are sometimes used to limit the density of warmth era, although slim-disk lasers function most effective with extremely doped crystals. A lot of laser goods do not reach the full effectiveness probable simply because these specifics haven't been thoroughly labored out.
GWU-Lasertechnik has over 30 yrs of working experience in distributing laser crystals. Pick GWU to get pleasure from our extensive information and in-area experience!
A higher injury threshold concerning pulse fluence or peak intensity is usually important for prime-energy 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：
晶体生长 晶体加工 镀膜能�?品质管理 研发能力 新闻中心
It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in a few sound mount which also functions being a heat sink. Bigger crystals are generally utilized for facet pumping e.g. with significant-ability diode bars.
The commonest laser-Energetic unusual earth ions and host media together with some typical emission wavelengths are revealed in the subsequent table:
A number of laser crystal materials are demonstrated in which some saturable absorber product is incorporated for passive Q switching of the laser.
Naturally, it is vitally desirable that a click here provided crystal excellent is produced constantly, While distinctive laser styles can have a distinct sensitivity to substance parameters.
You can find a wide range of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some vital teams of crystals are:
With that concept, one particular won't have to have yet another saturable absorber crystal, so that one might make much more compact Q-switched laser setups with reduce internal parasitic losses. Nevertheless, unwanted Negative effects can also take place, including obtaining unwanted valence states of your associated ions or Strength transfers.
GWU offers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a broad variety of technical specs. Aside from the effectively-established products, impressive crystals with exceptional properties like Yb:CALGO can open up new horizons for demanding laser programs. No matter irrespective of whether specific pieces for R & D uses are necessary or Price tag-productive numbers in modest, medium or big batches with in-time shipping for your generation line are required: GWU’s committed service helps you to find the finest core parts for your application.
Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical elements) �?that are utilised as gain media for solid-condition lasers. Typically, They're doped with both trivalent exceptional earth ions or changeover metallic ions.
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。
