Which geometry, dopant and doping focus in the obtain medium are most advantageous rely upon a number of factors. The out there pump resource (type of laser diode or lamp) and the envisaged pumping arrangement are crucial aspects, but the material itself also has some influence. Such as, titanium–sapphire lasers must be pumped with higher intensities, for which the form of a transversely cooled rod, operated with fairly smaller pump and laser beam diameter, is much more proper than e.
GWU presents all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) having a wide range of technical specs. Moreover the effectively-established elements, revolutionary crystals with remarkable Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Regardless of whether person pieces for R & D applications are needed or Value-efficient numbers in small, medium or large batches with in-time shipping and delivery for your production line are desired: GWU’s committed provider read more really helps to find the very best Main factors for your software.
Certainly, it is vitally desirable that a provided crystal good quality is made regularly, While various laser layouts can have a special sensitivity to substance parameters.
The most possible doping focus can rely strongly to the host product and its fabrication strategy.
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。
It is obvious that distinct purposes lead to really distinctive specifications on laser attain media. This is why, a wide assortment of different crystals are employed, and making the correct choice is essential for developing lasers with ideal effectiveness.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium ought to have a higher transparency (lower absorption and scattering) while in the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the standard of the fabric, determined by specifics on the fabrication system.
You can find an array of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline constructions. Some vital groups of crystals are:
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。
