The most typical laser-Energetic rare earth ions and host media together with some typical emission wavelengths are shown 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。
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（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 with the get medium are most advantageous rely on a number of aspects. The offered pump source (form of laser diode or lamp) as well as envisaged pumping arrangement are crucial factors, but the material itself also has some affect. One example is, titanium–sapphire lasers have to be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with comparatively little pump and laser beam diameter, is more appropriate than e.
GWU delivers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a wide a number of technical specs. Apart from the perfectly-proven resources, modern crystals with outstanding Qualities like Yb:CALGO can open new horizons for demanding laser programs. No matter whether or not personal items for R & D functions are needed or Price tag-effective numbers in small, medium or huge batches with in-time shipping for the production line are essential: GWU’s devoted assistance helps you to discover the best core components on your software.
Naturally, it is vitally fascinating that a specified crystal excellent is created persistently, Whilst unique laser designs might have a different sensitivity to substance parameters.
g. a thin disk. As A further example, Q-switched lasers access a greater population density within the upper laser level and are consequently a lot more delicate to quenching outcomes and Electrical power transfer processes; for that reason, a decreased doping density is usually suitable for these gadgets. For high-electric power lasers, lessen doping densities in many cases are used to limit the density get more info of warmth generation, Though slim-disk lasers function very best with highly doped crystals. Quite a few laser items do not get to the whole general performance opportunity mainly because this sort of details haven't been effectively worked out.
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。

Diverse crystalline components are really unique concerning their hardness and also other Qualities, which figure out with which solutions And the way easily they may be Reduce and polished with high quality.
GWU-Lasertechnik has more than thirty a long time of expertise in distributing laser crystals. Opt for GWU to take advantage of our broad information and in-area expertise!
With That idea, just one won't have to have a further saturable absorber crystal, to ensure that 1 may make a lot more compact Q-switched laser setups with reduced inner parasitic losses. On the other hand, unwelcome Negative effects may manifest, such as obtaining unwelcome valence states from the concerned ions or Electricity transfers.
