These tables incorporate only the commonest host crystals; lots of Other people exist, that happen to be much less usually applied.
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。
Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical products) �?which can be applied as attain media for strong-condition lasers. Usually, They are really doped with possibly trivalent rare earth ions or transition metal ions.

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the upper-state life time.
GWU provides all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a wide range of requirements. Moreover the very well-proven resources, progressive crystals with exceptional properties like Yb:CALGO can open new horizons for demanding laser purposes. It doesn't matter irrespective of whether particular person items for R & D purposes are required or Charge-productive figures in small, medium or substantial batches with in-time delivery for that production line are wanted: GWU’s devoted services really helps to find the ideal Main components to your software.
A higher floor high quality is naturally vital. Specifications of surface flatness are sometimes a lot better than . This can help to avoid the two scattering losses and wavefront distortions which could degrade the laser's beam excellent. On top of that, scratch and dig technical specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
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。
Those surfaces that happen to be handed by the laser beam are Commonly both oriented at Brewster's angle or have an anti-reflection coating.
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 should check here have a high transparency (very low absorption and scattering) while in the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the quality of the material, based on specifics of your fabrication approach.
With that concept, a single will not want an extra saturable absorber crystal, to ensure that 1 might make more compact Q-switched laser setups with lessen inside parasitic losses. Even so, undesirable Negative effects can also happen, like getting undesirable valence states of the included ions or energy transfers.
