These tables incorporate only the commonest host crystals; numerous others exist, which might be considerably less regularly used.

激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

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。

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the higher-condition life time.

GWU features all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a broad variety of requirements. Other than the effectively-founded elements, progressive crystals with outstanding Houses like Yb:CALGO can open up new horizons for demanding laser programs. Irrespective of regardless of whether unique parts for R & D purposes are necessary or Price tag-economical figures in tiny, medium or massive batches with in-time shipping and delivery for that output line are required: GWU’s devoted provider helps to find the finest Main parts on your application.

Obviously, it's very attractive that a specified crystal high quality is produced continually, Even though unique laser types can have another sensitivity to materials parameters.

g. a skinny disk. As One more case in point, Q-switched lasers reach a greater populace density inside the upper laser level and they are as a result much more delicate to quenching results Laser Crystal and Power transfer processes; therefore, a decrease doping density is usually appropriate for these products. For top-electric power lasers, decrease doping densities will often be accustomed to limit the density of warmth technology, Though thin-disk lasers function most effective with highly doped crystals. Lots of laser goods tend not to reach the total performance potential due to the fact such specifics haven't been adequately worked out.

Some laser crystal components happen to be shown in which some saturable absorber material is included for passive Q switching of the laser.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

It is obvious that different applications bring about very diverse prerequisites on laser get media. Due to this, a broad selection of various crystals are applied, and earning the proper decision is essential for setting up lasers with ideal general performance.

The medium must have a high transparency (reduced absorption and scattering) in the wavelength regions of pump and laser radiation, and great optical homogeneity. To some extent, this depends upon the quality of the material, determined by details on the fabrication procedure.

Using our promotion offer, you are able to Screen your symbol, further down below your product or service description, and these will been witnessed by many photonics professionals.

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。
