The commonest laser-active uncommon earth ions and host media together with some standard emission wavelengths are proven in the next table:
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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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 focus in the achieve medium are most beneficial count on many factors. The available pump source (type of laser diode or lamp) along with the envisaged pumping arrangement are very important aspects, but the material itself also has some influence. For instance, titanium–sapphire lasers have to be pumped with large intensities, for which the form of a transversely cooled rod, operated with comparatively smaller pump and laser beam diameter, is a lot more proper than e.
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a wide selection of technical specs. Besides the nicely-set up components, progressive crystals with fantastic Qualities check here like Yb:CALGO can open up new horizons for demanding laser purposes. It does not matter whether unique items for R & D reasons are required or Charge-productive numbers in smaller, medium or huge batches with in-time supply to the output line are essential: GWU’s focused service helps you to locate the most effective core factors to your software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
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。
Laser modeling and simulation can be utilized to reliably ascertain the optimum crystal Proportions, doping density And maybe values of supplemental parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

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 high transparency (low absorption and scattering) during the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by particulars of the fabrication method.
With that concept, a person will not need yet another saturable absorber crystal, so that one particular may well make additional compact Q-switched laser setups with lower internal parasitic losses. However, undesired Unwanted side effects could also take place, which include getting undesired valence states on the involved ions or energy transfers.
