Mode locking of a wavelength-swept laser
Optics Letters, 2005Self-starting, stable mode-locked pulses can be generated from a wavelength-swept laser through the interplay between an intracavity scanning filter and self-phase modulation. From an Er3+-doped fiber laser employing a scanning Fabry-Perot filter, 100 ps optical pulses are obtained at a 12-MHz repetition rate with center wavelengths that are swept over

Theory of mode-locked semiconductor lasers
IEEE Journal of Quantum Electronics, 1996We present a theoretical study of semiconductor mode-locked lasers at a phenomenological level. We use the slow absorber model of New and Haus, but extend the analysis by taking into account the shift in the gain maximum due to the changing number of carriers.

An investigation was made of the time structure of giant laser pulses emitted by a neodymium glass-fiber laser. Partial mode locking occurred within some mode groups. An explanation of this effect is provided.

For laser systems generating only axial modes, i.e. modes with Gaussian energy distribution, a phase correlation of the modes and an equal frequency spacing between the modes result in an oscillating pulse in the cavity; the outcoupled beam appears as a train of pulses.

A criterion for mode locking a semiconductor diode laser is proposed. The criterion is based on reducing the difference frequency associated with unequally spaced, longitudinal modes to a value smaller than the mode width narrowed by stimulated emission. An integrated GaAs-GaAlAs structure that satisfies this condition is described.
