Abstract
We present a novel scheme of reducing the spectral broadening effects of self phase modulation (SPM) in high-peak-power, narrow-band fiber lasers by preconditioning the input pulses of a master oscillator seeded high-peak-power fiber amplifier with a commercially available fiber-coupled phase modulator. We demonstrate an output emission linewidth reduction in a 1064 nm nanosecond pulse-width, 10 kW peak power fiber laser system. Modeling and measurements are presented for this system using a directly modulated diode seed laser and the resulting practical limitations imposed on SPM mitigation are discussed.
