Stable operation of a synchronously pumped colliding-pulse mode-locked ring dye laser.
Pulses of 100-fsec duration are obtained by synchronous pumping of a colliding-pulse ring dye laser with a mode-locked Ar(+)-ion laser. Stable operation of the synchronously pumped colliding-pulse mode-locked laser over hours was obtained by a suitable choice of the distance between the gain and the absorber in combination with an appropriate pump-pulse sequence.
متن کاملModelling colliding-pulse mode-locked semiconductor lasers
A discussion of three topics in the eld of non linear optics is presented We begin with the Colliding Pulse Mode locked CPM Quantum Well QW laser A large signal model consisting of a wave propagation equation for the electrical eld and a rate equation model for the material response is derived The wave propagation equation of the electrical eld is derived from Maxwell s equations in the slowly ...
متن کاملPulse propagation near zero group-velocity dispersion in a femtosecond dye laser.
The propagation of femtosecond pulses in a colliding-pulse mode-locked dye laser near zero group-velocity dispersion is studied. The pulse spectrum is shown to exhibit a double-peak structure. This structure and its dependence on the intracavity dispersion can be explained by nonlinear pulse propagation near zero dispersion. A value for the third-order dispersion of the laser cavity is deduced ...
متن کاملBuildup of steady-state subpicosecond and femtosecond pulses in a colliding-pulse mode-locked ring dye laser.
We show for the first time, to our knowledge, that the buildup time to steady-state femtosecond pulses in a typical colliding-pulse mode-locked dye laser (lambda = 620 nm) with compensating prisms is 15 microsec after the pulses have been completely modulated. For a similar laser without the compensating prisms, the buildup time is 40 microsec and exhibits interesting oscillatory behavior in th...
متن کاملExperimental investigation of anti-colliding pulse mode-locked semiconductor lasers.
We experimentally demonstrate anti-colliding pulse mode-locking (ACPML) in an integrated semiconductor laser. The device geometry consists of a gain section and a saturable absorber (SA) section located immediately next to one of the cavity facets. After depositing a low-reflection coating on the SA facet and a high-reflection coating on the gain section facet, the threshold is unchanged, while...
