双波长皮秒脉冲与可调谐脉宽产生的实验研究
Experimental study about generation of picosecond pulses with dual-wavelengths and tunable pulse-widths
摘要
Abstract
In order to improve the practicability of multi-wavelength optical pulse equipment , a stable dual-wavelength semiconductor fiber ring laser was proposed and demonstrated by using dual-wavelength principle . Effects of ring cavity dispersion, filter pulse-width and modulation depth on output pulse were discussed .Experimental results are that repetition rate of dual-wavelength pulses is 5.0GHz and typical pulse-width is 20ps.Dual-wavelength pulses have good side-mode suppression ratios of 29.1dB ( at 1554.75nm) and 29.7dB ( at 1557.21nm) with typical output powers of -6.7dBm and -6.1dBm respectively.Output spectra are very stable with peak power fluctuation less than 0.5dB.This study is of great significance for the study of terahertz source and multi-wavelength optical pulse equipment .关键词
