The 5-Second Trick For Laser Crystal
The 5-Second Trick For Laser Crystal
Blog Article
Laser modeling and simulation can be used to reliably identify the ideal crystal dimensions, doping density And maybe values of further parameters.
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 changeover cross-sections of pump and laser transitions and likewise the upper-state 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。
The maximum doable doping concentration can rely strongly around the host substance and its fabrication technique.

A high problems threshold with regards to pulse fluence or peak depth could be vital for prime-Electrical power amplifiers.
These ions permit the crystal to amplify light here with the laser wavelength via stimulated emission, when Strength is equipped for the crystal by using absorption of pump mild (�?optical pumping

These tables incorporate only the most typical host crystals; lots of Other folks exist, that happen to be a lot less routinely utilised.
The most typical laser-Energetic scarce earth ions and host media together with some usual emission wavelengths are proven in the next desk:
Several laser crystal products happen to be shown the place some saturable absorber materials is included for passive Q switching of a laser.
For several factors, composite crystals have become preferred. These Use a spatially different chemical composition and might be manufactured with special designs.
You can find a wide range of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some essential groups of crystals are:

Laser crystals are optical crystals �?generally single crystals (monocrystalline optical elements) �?which can be utilized as get media for stable-state lasers. Usually, They're doped with both trivalent uncommon earth ions or transition steel ions.
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。
