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 �?normally solitary crystals (monocrystalline optical supplies) �?that happen to be made use of as gain media for solid-state lasers. In most cases, They may be doped with possibly trivalent exceptional earth ions or transition metal ions.
Furthermore, some overall flexibility is shed in experiments if 1 are unable to try out absorbers with unique thickness or doping focus, for example, without the need of exchanging the laser crystal by itself.
Which geometry, dopant and doping focus on the gain medium are most useful count on numerous things. The offered pump source (kind of laser diode or lamp) and also the envisaged pumping arrangement are crucial aspects, but the material alone also has some impact. Such as, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is much more suitable than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Obviously, it is very appealing that a provided crystal high quality is made constantly, Even though distinctive laser models may have a special sensitivity to substance parameters.
The most possible doping focus can count strongly on the host materials and its fabrication approach.
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。
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 people surfaces that are passed with the laser beam are Typically 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 must have a significant transparency (lower absorption and scattering) inside the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the quality of the fabric, based check here on particulars on the fabrication system.
With That idea, just one won't need to have an extra saturable absorber crystal, so that a person may possibly make extra compact Q-switched laser setups with decrease inner parasitic losses. However, undesired Unwanted effects might also come about, including acquiring unwanted valence states on the associated ions or Power transfers.
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。
