Optically injected mode-locked laser
Physical Review E, 2011We study analytically and numerically a delay differential model of a passively mode-locked semiconductor laser subjected to a single frequency coherent injection. The width of the locking cone is calculated asymptotically in the limit of small injection and compared to that obtained by direct numerical integration of the model equations.

Ultrafast mode-locked laser in nanophotonic lithium niobate
Science, 2023Mode-locked lasers (MLLs) generate ultrashort pulses with peak powers substantially exceeding their average powers. However, integrated MLLs that drive ultrafast nanophotonic circuits have remained elusive because of their typically low peak powers, lack

SIAM Review, 2006
A comprehensive treatment is given for the formation of mode-locked soliton pulses in optical fiber and solid state lasers. The pulse dynamics is dominated by the interaction of the cubic Kerr nonlinearity and chromatic dispersion with an intensity-dependent perturbation provided by the mode-locking element in the laser cavity.

Colliding pulse mode locked laser
Optical Fiber Communication Conference. Technical Digest Postconference Edition. Trends in Optics and Photonics Vol.37 (IEEE Cat. No. 00CH37079), 2000The fabrication and performance of a colliding pulse-mode locked laser with an intracavity saturable absorber is described. The laser has a threshold current of 65 mA and differential efficiency of 0.04 mW/mA when coupled into a single-mode fiber. Mode-locked pulses with /spl sim/1 ps pulse width at /spl sim/10 GHz has been obtained.

Passive Mode-Locking Techniques of Lasers
International Journal of High Speed Electronics and Systems, 1997In the frequency domain, mode-locking of a laser is to "lock" the relative phase of various iongitudinal modes in order to form pulses. In many applications, passive mode-locking is superior to active mode-locking because the former does not need any external active sources as required for the latter.

Revisiting the physics of mode locking in lasers
SPIE Proceedings, 2014We present a way to describe mode locking through a master equation, derived from the laser Maxwell-Bloch equations, which take into account coherence in light-gain interaction. Our derivation shows that gain evolution on the fast time scale of the laser pulses must be considered, unlike in Haus master equation.

IEEE Journal of Selected Topics in Quantum Electronics, 2000
The evolution of the theory of mode-locking over the last three and a half decades is reviewed and some of the salient experiments are discussed in the context of the theory. The paper ends with two-cycle pulses of a mode-locked Ti:sapphire laser.

Application of a Mode-Locked Laser to Holography
Applied Optics, 1972A system that uses a mode-locked laser to record double exposure holograms of a rapidly changing object is described. A saturable absorber is used to mode-lock a ruby laser, producing a train of pulses of very short duration. Two of the pulses are selected by rapidly switching a Kerr cell shutter arrangement. When these two pulses are used to produce a
