The commonest laser-Energetic uncommon earth ions and host media along with some regular emission wavelengths are shown in the subsequent 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 �?typically single crystals (monocrystalline optical components) �?that happen to be made use of as gain media for sound-state lasers. Generally, They can be doped with either trivalent rare earth ions or changeover steel ions.

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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 fascinating that a provided crystal good quality is produced persistently, Despite the fact that various laser types may have a distinct sensitivity to product 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。
Some laser crystal elements are demonstrated in which some saturable absorber material is integrated for passive Q switching of the laser.
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 which can be handed via the laser beam are here Generally both oriented at Brewster's angle or have an anti-reflection coating.

For different factors, composite crystals are getting to be well-liked. These Have a very spatially various chemical composition and may be produced with Exclusive styles.
It may be oriented for in the vicinity of perpendicular incidence on the laser beam, or at Brewster's angle. It may be fixed in certain strong mount which also functions for a heat sink. Larger sized crystals are generally employed for side pumping e.g. with significant-power diode bars.
