These tables have only the most typical host crystals; quite a few others exist, which can be fewer usually used.
These ions permit the crystal to amplify mild within the laser wavelength by means of stimulated emission, when Electricity is supplied into the crystal via absorption of pump mild (�?optical pumping
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 gain medium are most advantageous count on many aspects. The offered pump source (sort of laser diode or lamp) as well as envisaged pumping arrangement are important elements, but the fabric itself also has some influence. Such as, titanium–sapphire lasers should be pumped with high intensities, for which the shape of the transversely cooled rod, operated with relatively compact 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。
Needless to say, it is very appealing that a presented crystal quality is generated consistently, Despite the fact that distinctive laser styles may have a unique sensitivity to material parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A couple of laser crystal elements are actually demonstrated in which some saturable absorber materials is integrated for passive Q switching of the laser.

All those surfaces that are passed because of the laser beam are Commonly both oriented at Brewster's angle or have an anti-reflection coating.
Different crystalline components are quite distinctive about their hardness as well as other properties, which ascertain with which methods and how effortlessly they can be Reduce and polished with good quality.
The medium must have a large Laser Crystal transparency (small absorption and scattering) while in the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the standard of the material, based on specifics from the fabrication method.
There may be a variety of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline structures. Some vital groups 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。
