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 focus on the attain medium are most advantageous rely upon numerous aspects. The obtainable pump supply (sort of laser diode or lamp) as well as the envisaged pumping arrangement are important elements, but the fabric by itself also has some impact. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the shape of a transversely cooled rod, operated with relatively compact pump and laser beam diameter, is much more appropriate than e.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
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 maximum doable doping concentration can rely strongly around the host substance and its fabrication method.
Laser modeling and simulation can be employed to reliably establish the the best possible crystal dimensions, doping density And maybe values of further parameters.
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。
All those surfaces which might be passed by the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出,过高的浓度可能导致消光效应,降低晶体的效率。
In 2017, we made the entire world’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely vast emission spectra drives the event of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Power, peak electricity, and repetition charge of solid-point out lasers, laser crystals will establish toward greater measurements, larger crystal top quality, and controllable essential performance.
It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in certain good mount which also functions to be more info a warmth sink. Larger sized crystals are generally used for facet pumping e.g. with high-electrical power diode bars.
