These tables consist of only the most typical host crystals; lots of Other individuals exist, which are significantly less routinely used.
These ions enable the crystal to amplify gentle for the laser wavelength through stimulated emission, when Vitality is equipped on the crystal via absorption of pump gentle (�?optical pumping
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical materials) �?which might be used as get media for strong-point out lasers. Normally, They are really doped with either trivalent unusual earth ions or changeover metallic ions.
激光晶体中活性离子的作用是什么? 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping focus from the obtain medium are most beneficial rely on several components. The available pump resource (sort of laser diode or lamp) as well as envisaged pumping arrangement are very important elements, but the material by itself also has some influence. Such as, titanium–sapphire lasers must be pumped with higher intensities, for which the form of a transversely cooled rod, operated with relatively small pump and laser beam diameter, is a lot more correct than e.
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。
A significant area high quality is not surprisingly vital. Specifications of surface flatness are sometimes a lot better than . This can help to avoid each scattering losses and wavefront distortions which might degrade the laser's beam good quality. Also, scratch and dig requirements
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。
The host crystal is a lot more than simply a method to repair the laser-active ions at specific positions in Place. A number of Qualities on the host product are important:
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。
All those surfaces that happen to be handed because of the laser beam are Generally either oriented at Brewster's angle or have an anti-reflection coating.
材料 激光晶体 晶体生长 光学性能 稀土离子 过渡族离子 elements laser crystal crystal development optical functionality scarce earth ions changeover team ions
The medium ought to have a significant transparency (lower absorption and scattering) inside the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the quality of the material, based on facts of your fabrication system.
With that concept, one would not need to have an additional saturable absorber crystal, so that 1 may make additional compact Q-switched laser setups with reduced interior parasitic losses. Nonetheless, undesired Uncomfortable side effects may happen, such as acquiring unwelcome valence states of the included ions or energy transfers.
