Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical components) �?that happen to be utilised as obtain media for strong-point out lasers. Normally, they are doped with both trivalent uncommon earth ions or changeover metal 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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-condition lifetime.

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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

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 handful of laser crystal products are demonstrated exactly where some saturable absorber material 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。

People surfaces that are passed with the laser beam are Usually possibly 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。

For many causes, composite crystals are getting to be well-liked. These Possess a spatially varying chemical composition and can be produced with special designs.

It could be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It may be set in some sound mount which also acts more info as a warmth sink. Greater crystals tend to be employed for facet pumping e.g. with superior-electricity diode bars.

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。
