Amplified Noise nonstationarity in a mode locked laser based on nonlinear polarization rotation
Optics Letters, 2019Co-Authors: Carlos Andres Perilla Rozo, Philippe Guay, Jeandaniel Deschenes, Jerome GenestAbstract:Beat note measurements between a mode-locked (ML) and a continuous-wave laser, as well as between two ML sources, were used to demonstrate that the sub-threshold, cavity filtered, Amplified spontaneous emission is not stationary, even when a fast mode-locking mechanism, such as nonlinear polarization rotation, is used to generate short pulses. A relatively small gain modulation of a few percent created by high-intensity pulses can produce a significant modulation of the Amplified Noise once synchronously accumulated over several cavity round-trips, even if the repetition rate is faster than the gain dynamics.

supercontinuum generation in highly nonlinear fibers using Amplified Noise like optical pulses
Optics Express, 2014Co-Authors: Shih Shian Lin, Shengkwang Hwang, Jiaming LiuAbstract:Supercontinuum generation in a highly nonlinear fiber pumped by Noise-like pulses from an erbium-doped fiber ring laser is investigated. To generate ultrabroad spectra, a fiber amplifier is used to boost the power launched into the highly nonlinear fiber. After amplification, not only the average power of the Noise-like pulses is enhanced but the spectrum of the pulses is also broadened due to nonlinear effects in the fiber amplifier. This leads to a reduction of the peak duration in their autocorrelation trace, suggesting a similar extent of pulse compression; by contrast, the pedestal duration increases only slightly, suggesting that the Noise-like characteristic is maintained. By controlling the pump power of the fiber amplifier, the compression ratio of the Noise-like pulse duration can be adjusted. Due to the pulse compression, supercontinuum generation with a broader spectrum is therefore feasible at a given average power level of the Noise-like pulses launched into the highly nonlinear fiber. As a result, supercontinuum generation with an optical spectrum spanning from 1208 to 2111 nm is achieved using a 1-m nonlinear fiber pumped by Amplified Noise-like pulses of 15.5 MHz repetition rate at an average power of 202 mW.
