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

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。

A high floor top quality is obviously vital. Specs of area flatness are sometimes better than . This will help to prevent both of those scattering losses and wavefront distortions which might degrade the laser's beam high-quality. Furthermore, scratch and dig technical specs

The utmost attainable doping concentration can depend strongly on the host material and its fabrication approach.

Laser modeling and simulation can be employed to reliably establish the optimum crystal Proportions, doping density And perhaps values of additional parameters.

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 clear that diverse applications produce very different demands on laser get media. Because of this, a wide range of various crystals are utilised, and earning the best preference is essential for setting up lasers with optimum effectiveness.

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。

The medium must have a high transparency (reduced absorption and scattering) during the wavelength areas of pump and laser radiation, and superior optical homogeneity. To some extent, this is determined by the caliber of the material, determined by specifics in the Laser Crystal fabrication course of action.

There's a wide array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline constructions. Some vital teams 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。
