Diverse crystalline materials are quite distinct about their hardness together with other Attributes, which establish with which solutions And just how simply they can be Minimize and polished with top quality.
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the higher-condition life time.
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。
The utmost possible doping focus can depend strongly on the host material and its fabrication system.
g. a skinny disk. As An additional illustration, Q-switched lasers arrive at a greater population density during the higher laser stage and therefore are as a result much more delicate to quenching consequences and energy transfer processes; consequently, a lessen doping density is usually suitable for these units. For high-ability lasers, decrease doping densities are sometimes used to limit the density of heat technology, Even though thin-disk lasers work best with hugely doped crystals. Lots of laser items usually do not get to the entire performance likely simply because these types of facts have not been effectively worked out.

A high damage threshold in terms of pulse fluence or peak depth is often critical for high-Power amplifiers.
These ions permit the crystal to amplify gentle at the laser wavelength by way of stimulated emission, when Vitality is provided to the crystal via absorption of pump light-weight (�?optical pumping

These tables have only the commonest host crystals; a lot of Other folks exist, which might be considerably less frequently utilized.
The commonest laser-Energetic uncommon earth ions and host media together with some typical emission wavelengths are revealed in the subsequent table:
Individuals surfaces that happen to be handed through the laser beam are Generally possibly oriented at Brewster's angle or have an anti-reflection coating.
Of course, it's very fascinating that a offered crystal excellent is manufactured consistently, Whilst distinctive laser layouts may have a unique Laser Crystal sensitivity to material parameters.
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。
With that concept, just one will not require an extra saturable absorber crystal, to ensure that a single may possibly make additional compact Q-switched laser setups with decrease inner parasitic losses. Nonetheless, unwelcome Unintended effects may additionally take place, such as acquiring unwanted valence states of your included ions or energy transfers.

Laser crystals are optical crystals �?usually single crystals (monocrystalline optical supplies) �?that happen to be made use of as obtain media for solid-state lasers. Usually, They're doped with both trivalent unusual earth ions or transition metal ions.
