The commonest laser-active scarce earth ions and host media along with some typical emission wavelengths are shown in the next desk:

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 �?usually solitary crystals (monocrystalline optical elements) �?that are utilised as get media for solid-condition lasers. Usually, They may be doped with possibly trivalent uncommon earth ions or changeover metallic 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 of the acquire medium are most advantageous depend on several factors. The available pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial variables, but the material alone also has some affect. For instance, titanium–sapphire lasers have to be pumped with large intensities, for which the shape of a transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is more correct than e.

Naturally, it's very fascinating that a presented crystal excellent is created constantly, Despite the fact that distinct laser styles might have a distinct sensitivity to material parameters.

The utmost possible doping concentration can count strongly within the host product and its fabrication approach.

The host crystal is a lot more than simply a way to fix the laser-Lively ions at selected positions in Place. Numerous Homes of the host material are important:

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

Those surfaces that happen to be passed by the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.

For different factors, composite crystals are becoming popular. These Have got a spatially various chemical composition and may be made with Distinctive designs.

Employing our advertising deal, you are able to display your brand, further under your products description, and these will been observed by lots of photonics experts.

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。
