Demonstration of fiber pulsed light source at 1.6 microns with adjustable pulse
A novel practical 1.66-micron pulse light source with adjustable pulse duration is proposed. A 2.5-km Raman fiber is placed into a ring type Q-switched erbium-doped fiber laser (Q-EDFL), serving as both delay line fiber and Raman gain medium so that in addition to the wavelength shifted to 1.6 micr
