These tables contain only the commonest host crystals; a lot of Other folks exist, which are fewer regularly used.
In this article you are able to submit inquiries and remarks. In terms of they get approved via the writer, they may appear previously mentioned this paragraph along with the author’s solution. The author will choose acceptance dependant on certain criteria. Basically, the issue has to be of sufficiently broad interest.
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
Which geometry, dopant and doping focus of the achieve medium are most useful depend upon quite a few variables. The accessible pump supply (variety of laser diode or lamp) along with the envisaged pumping arrangement are crucial aspects, but the material alone also has some affect. For instance, titanium–sapphire lasers should be pumped with high intensities, for which the form of the transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is a lot more suitable than e.
GWU provides all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a broad number of specs. Aside from the very well-recognized products, ground breaking crystals with outstanding Attributes like Yb:CALGO can open up new horizons for demanding laser purposes. It does not matter whether individual parts for R & D uses are expected or Charge-successful quantities in smaller, medium or massive batches with in-time shipping and delivery for your production line are desired: GWU’s committed support helps to locate the ideal core factors on your application.
A superior floor high quality is of course significant. Specs of area flatness are sometimes better than . This can help in order to avoid both scattering losses and wavefront distortions which often can degrade the laser's beam high quality. Also, scratch and dig specs
The most feasible doping concentration can rely strongly to the host material and its fabrication approach.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
All those surfaces that happen to be passed because of the laser beam are Typically either oriented at Brewster's angle or have an anti-reflection coating.

The medium should have a high transparency (reduced absorption and scattering) inside the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the caliber of the check here material, determined by aspects of your fabrication process.
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It might be fastened in a few sound mount which also acts as being a warmth sink. Greater crystals are usually useful for facet pumping e.g. with higher-ability diode bars.
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。
