The most typical laser-Energetic exceptional earth ions and host media along with some regular emission wavelengths are shown in the subsequent desk:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?generally single crystals (monocrystalline optical elements) �?which can be used as achieve media for good-state lasers. Typically, They're doped with both trivalent scarce earth ions or transition metallic 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。
This is not hard to perform: just locate the lock icon before the URL within the tackle bar and drag that to the bookmark toolbar Along with the mouse. In case you locate the bookmark entry way too long, you may ideal-click on it to edit the text, e.g. working with "RP Enc" instead of "RP Photonics Encyclopedia".
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。
Not surprisingly, it's very fascinating that a provided crystal high quality is produced persistently, Though distinct laser styles might have a distinct sensitivity to materials 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。
A handful of laser crystal components have been demonstrated in which some saturable absorber product is incorporated for passive Q switching of the 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。
These surfaces which might be passed with the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.
Various crystalline supplies are certainly different relating to their hardness and other properties, which identify with which strategies And just how conveniently they can be Reduce and polished with good quality.
The medium ought to have a substantial transparency (reduced absorption and scattering) in the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this is dependent upon the read more standard of the fabric, based on particulars of your fabrication approach.
It may be oriented for close to perpendicular incidence on the laser beam, or at Brewster's angle. It could be preset in certain good mount which also functions for a warmth sink. Much larger crystals usually are employed for aspect pumping e.g. with higher-energy diode bars.
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。
