These tables comprise only the commonest host crystals; numerous Other individuals exist, which might be fewer often utilised.
These ions permit the crystal to amplify light within the laser wavelength by means of stimulated emission, when Vitality is equipped on the crystal by means of absorption of pump mild (�?optical pumping
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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 accomplish: just locate the lock icon before the URL inside the handle bar and drag that towards the bookmark toolbar Together with the mouse. Just in case you locate the bookmark entry too extensive, you may appropriate-simply click it to edit the text, e.g. employing "RP Enc" in lieu of "RP Photonics Encyclopedia".
GWU presents all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a wide range of requirements. In addition to the nicely-established materials, innovative crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser applications. No matter whether particular person pieces for R & D applications are essential or Price-economical numbers in compact, medium or huge batches with in-time supply for your output line are necessary: GWU’s committed service helps you to find the ideal Main components to your software.
A superior area quality is needless to say significant. Technical specs of floor flatness are often better than . This assists to prevent equally scattering losses and wavefront distortions which could degrade the laser's beam excellent. On top of that, scratch and dig technical specs
The maximum probable doping concentration can count strongly to the host materials and its fabrication system.
The host crystal is much more than just a means to fix the laser-Lively ions at particular positions in Area. Quite a few Houses from the host content are very important:
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。
Those people surfaces which might be passed with the laser beam are Usually possibly more info oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a higher transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the quality of the fabric, based on particulars on the fabrication approach.
It may be oriented for near perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in certain stable mount which also acts as a warmth sink. Larger sized crystals tend to be useful for aspect pumping e.g. with substantial-electrical power diode bars.
