The Ultimate Guide To Laser Crystal
These tables incorporate only the most typical host crystals; many others exist, which might be considerably less commonly employed.These ions help the crystal to amplify gentle at the laser wavelength by means of stimulated emission, when Electricity is equipped to the crystal through absorption of pump light-weight (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-point out life span.

Needless to say, it is vitally appealing that a presented crystal quality is made consistently, Whilst diverse laser types might have a distinct 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。
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Distinct crystalline elements are certainly distinctive relating to their hardness together with other Houses, which establish with which procedures And just how very easily they may be Slash and polished with top quality.
The medium ought to have a higher transparency (lower absorption and scattering) during the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, determined by particulars of the fabrication method.
With that concept, just one does not want yet another saturable absorber crystal, to ensure one may possibly make more compact Q-switched click here laser setups with reduced inside parasitic losses. Having said that, unwanted Uncomfortable side effects might also manifest, such as obtaining unwanted valence states from the involved ions or Vitality transfers.
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。
