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。
Which geometry, dopant and doping concentration of the acquire medium are most beneficial depend on many aspects. The readily available pump supply (variety of laser diode or lamp) as well as the envisaged pumping arrangement are essential variables, but the material by itself also has some influence. One example is, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with reasonably tiny pump and laser beam diameter, is more appropriate than e.
GWU delivers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) by using a wide range of specifications. In addition to the properly-recognized resources, modern crystals with superb properties like Yb:CALGO can open new horizons for demanding laser programs. It does not matter whether or not specific parts for R & D applications are demanded or Expense-productive quantities in smaller, medium or massive batches with in-time shipping and delivery with the output line are required: GWU’s devoted provider helps to locate the most effective Main components for your application.
Needless to say, it's very desirable that a presented crystal high-quality is made consistently, Despite the fact that distinct laser layouts can have a distinct sensitivity to material parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
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。

GWU-Lasertechnik has a lot more than thirty a long time of expertise in distributing laser crystals. Opt for GWU to reap the benefits of our huge knowledge and in-subject working experience!
With That idea, 1 here will not require yet another saturable absorber crystal, in order that a single could make a lot more compact Q-switched laser setups with reduced inside parasitic losses. Even so, undesirable Unwanted effects may additionally take place, for example obtaining unwelcome valence states of your included ions or Power transfers.
