Machine learning-based pulse characterization in figure-eight mode-locked lasers

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...

Pump pulse effects in synchronously pumped mode-locked dye lasers

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...

Pulse Broadening in Injection Mode Locked Tea Co 2 Lasers

Injection mode locking of large-aperture TEA CO 2 lasers makes it possible to generate nanosecond pulses with high intensities [ 1 3 ] . It was shown by Dyer and Perera [6] that by injection mode locking the width of the amplified pulse depends on many variables, such as the width of the injected pulse from the master oscillator and the gas pressure of the slave oscillator. They studied the bro...
