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 �?ordinarily solitary crystals (monocrystalline optical elements) �?that are utilised as get media for solid-state lasers. Normally, They can be doped with both trivalent exceptional earth ions or transition metal ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping focus with the achieve medium are most advantageous depend on several aspects. The readily available pump resource (type of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the material alone also has some affect. For instance, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with fairly little pump and laser beam diameter, is a lot more suitable than e.

A superior surface top quality is obviously significant. Technical specs of area flatness tend to be better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam top quality. Furthermore, scratch and dig technical specs
The utmost possible doping concentration can count strongly within the host product and its fabrication method.
The host crystal is considerably more than just a more info method to repair the laser-Lively ions at selected positions in Place. Many properties with the host product are crucial:

People surfaces which can be handed with the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

For different explanations, composite crystals are becoming well-liked. These Have a very spatially various chemical composition and might be built with Specific designs.
There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline constructions. Some significant teams of crystals are:
