These tables incorporate only the most common host crystals; lots of Other individuals exist, that happen to be significantly less frequently utilized.
These ions help the crystal to amplify gentle for the laser wavelength by means of stimulated emission, when energy is equipped into the crystal by means of absorption of pump light-weight (�?optical pumping
Laser crystals are optical crystals �?ordinarily solitary crystals (monocrystalline optical resources) �?which can be made use of as get media for reliable-point out lasers. Normally, They can be doped with both trivalent rare earth ions or transition metal 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。
Which geometry, dopant and doping concentration on the acquire medium are most advantageous rely upon a number of factors. The accessible pump resource (variety of laser diode or lamp) plus the envisaged pumping arrangement are important aspects, but the fabric alone also has some influence. For instance, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of a transversely cooled rod, operated with relatively tiny pump and laser beam diameter, is much more acceptable than e.
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a broad variety of specifications. Apart from the effectively-set up components, modern crystals with remarkable Qualities like Yb:CALGO can open new horizons for more info demanding laser purposes. It doesn't matter whether individual parts for R & D uses are necessary or cost-productive figures in modest, medium or huge batches with in-time delivery for the manufacturing line are needed: GWU’s committed support helps to locate the greatest Main elements for your software.
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 most possible doping concentration can rely strongly about the host product and its fabrication method.
A couple of laser crystal materials are demonstrated where some saturable absorber product is integrated for passive Q switching of 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。

GWU-Lasertechnik has in excess of thirty several years of experience in distributing laser crystals. Choose GWU to gain from our wide information As well as in-industry encounter!
It could be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It could be fixed in some sound mount which also functions as a warmth sink. Larger crystals are frequently useful for side pumping e.g. with significant-energy diode bars.
