Real Time Measurements of Spectral Instabilities in Ultrafast Fibre Laser Systems
International audience;
Real-time measurement of soliton-similariton explosions and intermittence instabilities in a mode-locked fibre laser
International audience; Ultrafast mode-locked lasers are well-known to display a rich variety of unstable dissipative soliton dynamics resulting from the interplay of nonlinearity, dispersion and dissipation. Although laser instabilities have been known and studied in depth for many years, their properties have recently received greatly renewed attention because of the development of time and frequency domain techniques that allow laser dynamics and instabilities to be measured in real-time. This has allowed the variations in circulating pulse characteristics to be examined on a roundtrip to roundtrip basis, providing a new window into understanding these instabilities and how they develop …
Real-Time Measurements of Ultrafast Instabilities in Nonlinear Fiber Optics: Recent Advances
Recent years have seen renewed interest in the study of nonlinear fibre laser and propagation dynamics through the use of real-time measurement techniques for non-repetitive ultrafast optical signals. In this paper we review our recent work in this field using dispersive Fourier Transform and Time Lens techniques.
