Abstract
This work reports the experimental demonstration of supercontinuum (SC) generation with broad spectral output of 950 nm maximum or a 3.7 dB variation within the range from 1300 to 1600 nm and demonstrate how some fiber properties enhance nonlinearities and shows different SC output spectrum. Broad spectrum was achieved throughout a subnanosecond microchip pulsed laser operating at 1064 nm. Three different conventional fibers were employed: highnumerical aperture fiber (HNAF), dispersion shifted fiber (DSF) and single mode fiber (SMF). SMF was wrapped in different diameters to induce fiber losses. Several combinations of these three fibers and diameters resulted in high spectral width as well as high flatness in the telecom band.
