摘要
在可调频外腔半导体激光器（ＥＣＬＤ）中，选频元件的响应函数具有一定的频谱宽度，本文研究了该宽度对外腔半导体激光器的影响，导出了为实现外腔半导体激光器的连续调谐所需的该宽度的上限的表达式。
It is known that the responding function of the tuning element in a tunable external cavity semiconductor laser (ECLD) has a finite spectral width. Effects of this finite width on the characteristics of the ECLD have been studied. Expressions of the upper bound of the spectral width and the frequency difference between the peak of the grating reflection and the laser radiation have been derived for the case where a continuous tuning of the ECLD is required.
