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 one crystals (monocrystalline optical components) �?which are applied as acquire media for reliable-point out lasers. Normally, They are really doped with either trivalent unusual 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 concentration of the gain medium are most useful count on quite a few things. The offered pump supply (kind of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric by itself also has some influence. For example, titanium–sapphire lasers should be pumped with large intensities, for which the form of a transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more appropriate than e.

Obviously, it is extremely desirable that a offered crystal high quality is produced continuously, Whilst diverse laser patterns might have a distinct sensitivity to materials parameters.

The utmost possible doping focus can depend strongly on the host content and its fabrication method.

The host crystal is considerably more than simply a method to fix the laser-active ions at specific positions in Place. A number of Qualities on the host get more info substance are important:

It is apparent that distinct programs cause quite diverse necessities on laser achieve media. This is why, a broad assortment of different crystals are used, and earning the appropriate choice is important for setting up lasers with optimum performance.

For different good reasons, composite crystals are becoming popular. These Use a spatially varying chemical composition and may be manufactured with Exclusive styles.

There exists a variety of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline structures. Some significant teams of crystals are:

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
