Abstract

We present a Q-switched neodymium-doped fiber laser (NDFL) that employs a polyaniline (PANI) saturable absorber (SA) in an all-fiber configuration. The NDFL generated stable Q-switched pulses, achieving a minimum pulse duration of 5.31 µs and a maximum repetition rate of 35.2 kHz. Operating at 1089.2 nm, the laser produced pulse energies of 3.72 nJ at a maximum pumping of 141.4 mW at 808 nm. The output demonstrated remarkable stability, with a signal-to-background noise ratio of 52 dB at the main frequency. This work represents the first demonstration of a PANI-based Q-switched NDFL operating in the one-micron wavelength region. [ABSTRACT FROM AUTHOR]
