The most typical laser-Lively uncommon earth ions and host media together with some common emission wavelengths are proven in the next desk:
These ions enable the crystal to amplify mild within the laser wavelength by way of stimulated emission, when Electrical power is provided towards the crystal by using absorption of pump mild (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
Which geometry, dopant and doping concentration of your acquire medium are most beneficial count on numerous elements. The out there pump source (sort of laser diode or lamp) plus the envisaged pumping arrangement are essential components, but the fabric alone also has some impact. For example, titanium–sapphire lasers must be pumped with superior intensities, for which the shape of the transversely cooled rod, operated with rather little pump and laser beam diameter, is much more acceptable than e.
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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The utmost feasible doping concentration can count strongly within the host product and its fabrication approach.
Laser modeling and simulation can be employed to reliably identify the optimum crystal Proportions, read more doping density and possibly values of extra parameters.
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。

Distinct crystalline elements are extremely unique concerning their hardness and other Qualities, which determine with which approaches And the way very easily they may be Lower and polished with high quality.
GWU-Lasertechnik has greater than thirty several years of encounter in distributing laser crystals. Choose GWU to reap the benefits of our huge knowledge As well as in-field working experience!
With That idea, just one does not need an extra saturable absorber crystal, so that one might make far more compact Q-switched laser setups with decrease internal parasitic losses. Having said that, undesirable Negative effects could also arise, like acquiring unwanted valence states of your involved ions or Vitality transfers.
