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。

g. a skinny disk. As A different instance, Q-switched lasers get to a higher population density while in the higher laser degree and are therefore additional delicate to quenching results and Power transfer processes; for that reason, a lower doping density is frequently suitable for these units. For top-ability lasers, reduce doping densities will often be accustomed to Restrict the density of warmth generation, While thin-disk lasers get the job done finest with extremely doped crystals. Many laser goods will not reach the total functionality opportunity for the reason that this sort of details haven't been correctly labored out.

A few laser crystal materials are demonstrated wherever some saturable absorber content is incorporated 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。

GWU-Lasertechnik has over 30 several years of working experience in distributing laser crystals. Opt for GWU to gain from our broad expertise As well as in-subject practical experience!

With That idea, 1 would not want an additional saturable absorber crystal, in order that 1 may well make additional compact Q-switched laser setups with decreased inner parasitic losses. Nevertheless, undesired Uncomfortable side effects may come about, including getting undesirable valence states of the included ions or Vitality transfers.

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
