A Review Of Laser Crystal

A Review Of Laser Crystal

Blog Article

These tables contain only the commonest host crystals; many Other folks exist, which are significantly less often utilised.

These ions allow the crystal to amplify gentle on the laser wavelength by using stimulated emission, when Electrical power is equipped for the crystal by using absorption of pump light (�?optical pumping

Laser crystals are optical crystals �?normally one crystals (monocrystalline optical elements) �?which are utilised as acquire media for strong-state lasers. Generally, They are really doped with possibly trivalent uncommon earth ions or changeover metallic 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。

Needless to say, it is very attractive that a presented crystal quality is manufactured persistently, While various laser layouts can have a unique sensitivity to material parameters.

The maximum possible doping focus can count strongly on the host product and its fabrication method.

The host crystal is much more than just a method to fix the laser-Lively ions at particular positions in Room. Many Homes with the host product are very important:

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。

For quasi-three-level laser gain media or maybe 3-degree obtain media, 1 often must limit the length to a price which can be too quick for effective pump absorption, as reabsorption more info outcomes would otherwise spoil the functionality. For facet pumping, supplemental concerns come into Perform; Aside from efficient pump absorption, it is vital to obtain an acceptable spatial shape on the obtain profile.

For many good reasons, composite crystals are getting to be preferred. These have a spatially varying chemical composition and will be made with Unique styles.

There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some important 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。
