The most common laser-active scarce earth ions and host media along with some common emission wavelengths are proven in the following 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 one crystals (monocrystalline optical elements) �?which might be utilised as achieve media for sound-state lasers. Most often, These are doped with both trivalent rare earth ions or changeover steel 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。
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：
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
Not surprisingly, it is extremely fascinating that a given crystal top quality is manufactured regularly, While different laser types might have a different sensitivity to materials 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 few laser crystal elements have already been shown the place some saturable absorber materials is included for passive Q switching of a 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。
It is obvious that distinct programs result in very different prerequisites on laser get media. This is why, a broad variety of various crystals are applied, and generating the correct option is important for setting up lasers with optimum general performance.

GWU-Lasertechnik has over thirty decades of expertise in distributing laser crystals. Decide on GWU to take pleasure in our broad expertise As well as in-industry encounter!
It may be oriented for around perpendicular website incidence with the laser beam, or at Brewster's angle. It might be fixed in certain strong mount which also acts for a warmth sink. Larger crystals are generally employed for aspect pumping e.g. with significant-ability diode bars.
