These ions allow the crystal to amplify gentle in the laser wavelength by means of stimulated emission, when Power is provided to the crystal through 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。
This is not hard to accomplish: just discover the lock icon before the URL during the handle bar and drag that to the bookmark toolbar With all the mouse. Just in case you locate the bookmark entry far too extensive, you can correct-click it to edit the text, e.g. employing "RP Enc" in place of "RP Photonics Encyclopedia".
GWU provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) which has a wide selection of specifications. Other than the very well-proven supplies, ground breaking crystals with remarkable Qualities like Yb:CALGO can open up new horizons for demanding laser applications. No matter irrespective of whether specific parts for R & D functions are demanded or Price-successful quantities in tiny, medium or substantial batches with in-time delivery for your creation line are required: GWU’s devoted assistance really helps to locate the greatest core parts for your personal software.
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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 number of laser crystal materials are shown in which some saturable absorber product is incorporated for passive Q switching of the laser.

The medium should have a superior transparency (lower absorption and scattering) inside the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the caliber of the material, determined by facts with the fabrication method.
It may be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be set in some solid mount which also functions to be a warmth sink. More substantial crystals usually are employed for side pumping e.g. with read more high-power diode bars.
