Pump pulse effects in synchronously pumped mode-locked dye lasers

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.

Modelling 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 ...

Pulse Timing in CW Mode - locked Nd : YLF Lasers

The influence of various noise sources on CW mode-locked laser pulse timing is investigated. Measurements are performed on a Nd:YLF laser to confirm timing dependence on cavity length and acousto-optic modulator characteristics. Simple models are used to understand and predict the influence of thermal load on the modulator and to predict the sensitivity of timing to pump and cavity loss modulat...

Analysis of Temporal Pulse Development in Passively Mode-Locked Lasers

Pulse-shortening and pulse broadening effects in passively mode-locked lasers are analysed. A steady-state pulse duration limit is calculated and compared with round-trip simulations. The numerical calculations apply to a picosecond N d : glass laser. Methods of short-pulse generation are discussed. PACS: 42.55R, 42.60D, 42.65 In passively mode-locked pulsed lasers the statistical spontaneous e...
