Experiments were carried out in order to investigate efficient second-harmonic generation in phosphor-doped glass fibers. Peak conversion efficiencies > 5% corresponding to peak powers> 1 kW at 0.53 microm have been obtained. By measuring the side light emitted and also by cutting the fibers, both the second-harmonic output power and the generation rate were studied along the fiber. Other measurements, including the polarization and mode structure of the frequency-doubled output, are also described.
为了研究掺磷玻璃纤维中的高效二次谐波产生，进行了相关实验。在0.53微米波长处，已获得对应于峰值功率>1千瓦的峰值转换效率>5%。通过测量侧向发射光以及切割纤维，研究了沿纤维的二次谐波输出功率和产生速率。还描述了其他测量，包括倍频输出的偏振和模式结构。
