These tables contain only the most common host crystals; a lot of Many others exist, that are considerably less regularly employed.
These ions enable the crystal to amplify light in the laser wavelength by way of stimulated emission, when Power is supplied towards the crystal by way of 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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-condition life time.
GWU delivers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) using a wide variety of requirements. Besides the nicely-founded supplies, impressive crystals with outstanding Homes like Yb:CALGO can open new horizons for demanding laser programs. Despite irrespective of whether person pieces for R & D reasons are necessary or Value-successful figures in tiny, medium or massive batches with in-time shipping and delivery for the manufacturing line are necessary: GWU’s devoted service helps you to discover the finest core components 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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be utilized to reliably identify the optimum crystal Proportions, doping density And maybe values of additional 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。
For quasi-a few-degree laser get media or perhaps three-degree get media, a person often really should Restrict the size to a worth that is also small for economical pump absorption, as reabsorption consequences would otherwise spoil the efficiency. For aspect pumping, further issues arrive into Engage in; In addition to effective pump absorption, it is necessary to obtain an acceptable spatial form in the acquire profile.
Different crystalline supplies are incredibly various concerning their click here hardness and other Homes, which ascertain with which procedures And exactly how easily they may be Slash and polished with high quality.
For a variety of factors, composite crystals have become preferred. These Have got a spatially different chemical composition and can be created with Specific styles.
It could be oriented for near perpendicular incidence in the laser beam, or at Brewster's angle. It can be preset in certain reliable mount which also acts to be a heat sink. Much larger crystals are often useful for aspect pumping e.g. with high-ability diode bars.
