摘　　要：报道了实验研究连续１０５３ｎｍＮｄ３＋ＹＬＦ激光泵浦国产掺Ｔｍ３＋石英光纤产生紫外（３８７．４ｎｍ）、蓝光（４７７．４）、红光（６５１．４）、近红外光（８０２．９ｎｍ）的频率上转换荧光的实验结果。测量了荧光发射光谱以及发光强度随泵浦功率的变化，并给出了实验结果的初步机理解释。Frequency upconverted fluorescence from UV to infrared(387.4nm,477.4nm,651.4nm, 802.9nm )has been observed and studied in homemade Tm 3+ doped silica fibers pumped by CW Nd 3+ :YLF laser at 1053nm.The pump mechanism is given that red and blue light are produced through stepwise three photo absorption and infrared light is done through stepwise two photo absorption.The shoulder peak of blue and red light are also analysed with all fluorescence spectra being measured.
