Fractals, complex shapes with structure at multiple scales, have long been observed in
nature: as symmetric fractals in plants and sea shells, and as statistical fractals in clouds …

Deep blue lasers are one of the prominent technological advancements that resulted in a
Nobel prize in 2014 for the invention of an efficient InGaN-based active medium. Such delay …

We present for the first time, to the best of our knowledge, the influence of spherical
aberration on the beam quality of a single-stage laser amplifier. We set up an amplifier with …

Experimental observations of beam profile evolution and beam quality changes in an
asymmetrical diode-end-pumped laser oscillator are presented. The beam intensity …

For laser users, the usual Gaussian beam (GB) may not always be the best intensity profile.
Often, a preferred option is a Flat-Top (FT) beam which is generally obtained by using …

Résumé La thèse comporte deux chapitres; le premier chapitre porte sur le miroir Fox-Smith
(FSM) qui a longtemps été utilisé dans un arrangement de cavité laser à trois miroirs pour …

Abstract The Fox-Smith mirror (FSM) has long been used in a three-mirror laser cavity
arrangement for forcing the laser oscillation on a single-longitudinal mode. However, its …

The subject of this research is to investigating the advantages of a special stable resonator
relative to the flat-symetric stable resonator scheme in high power pumped Nd: YAG lasers …

Traditional laser systems are usually designed in such a way as to produce the fundamental
Gaussian mode. The Gaussian mode, however, is not ideally suitable for all applications at …
