Laser crystals are optical crystals �?generally one crystals (monocrystalline optical resources) �?that are applied as acquire media for solid-condition lasers. In most cases, These are doped with either trivalent uncommon earth ions or changeover metallic ions.
On top of that, some flexibility is misplaced in experiments if just one cannot Check out absorbers with distinctive thickness or doping focus, as an example, with out exchanging the laser crystal by itself.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the higher-point out life span.
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。
Obviously, it is very attractive that a specified crystal excellent is developed persistently, although unique laser models can have a different sensitivity to product parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
Some laser crystal components have been demonstrated where some saturable absorber substance is included for passive Q switching of Laser Crystal a laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

The medium ought to have a large transparency (reduced absorption and scattering) during the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this depends on the caliber of the material, determined by details with the fabrication method.
Applying our promoting package, it is possible to display your emblem, even further beneath your merchandise description, and these will been seen by several photonics industry experts.
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。
