Dynamic modal analysis of monolithic mode-locked semiconductor lasers [PDF]
, 2003 We analyze the advantages and applicability limits of the mode-coupling approach to active, passive, hybrid, and harmonic mode-locking in diode lasers. A simple, computationally efficient numerical model is proposed and applied to several traditional and

Passive harmonic mode locking in soliton fiber lasers [PDF]
Journal of the Optical Society of America B, 1997 We show that low time jitter of a harmonic passively mode-locked laser can be obtained at repetition rates close to acoustic eigen-frequencies of the optical fibre.

Polarization attractors in harmonic mode-locked fiber laser [PDF]
Optics Express, 2014 We report on a polarimetry of harmonic mode-locked erbium-doped fiber laser with carbon nanotubes saturable absorber. We find new types of vector solitons with locked, switching and precessing states of polarization. The underlying physics presents interplay between birefringence of a laser cavity created by polarization controller along with light ...

Harmonically mode-locked Yb:CALGO laser oscillator
Optics Express, 2017 We present a passively mode-locked Yb:CALGO oscillator with harmonic repetition rate operation up to the third order. It is operated in the solitary regime with a fundamental roundtrip rate of 94 MHz and pulse durations between 200 fs and 600 fs. Harmonic operation was observed being stable for several days.

Decaying dynamics of harmonic mode-locking in a SESAM-based mode-locked fiber laser
Optics Express, 2023 The entire decaying dynamics of harmonic mode-locking (HML) are studied utilizing the dispersive Fourier transform (DFT) technique in a SESAM-based mode-locked fiber laser. It is unveiled that the harmonic solitons do not disappear directly, but undergo transitional processes from the higher-order HML to the lower-order HML and then to the fundamental ...
