Propagation autoguidée soliton lors de la génération de second harmonique dans un cristal de PPLN

Autor: Francesco Gringoli, Pete Smith, C. De Angelis, Alain Barthelemy, D.C. Hanna, Graeme W. Ross, Vincent Couderc, B. Bourliaguet

Publikováno v: Scopus-Elsevier

We report what are to our knowledge the first observation and characterization of quadratic spatial solitons in periodically poled lithium niobate (PPLN). Using an Nd:YAG (1064 nm) source, we observed self-trapped solitary-wave propagation over more

Amélioration de la brillance d'oscillateurs paramétriques optiques pulsés par filtrage intracavité

Autor: Alain Barthelemy, Vincent Kermène, B. Bourliaguet, A. Mugnier, Claude Froehly

Publikováno v: Le Journal de Physique IV. 10:Pr8-193

We describe the design and operation of a pulsed optical parametric oscillator (OPO) with an intracavity spatial filter. This filter designed to select a single high order transverse mode improves the brightness of the generated parametric waves by d

4-W and 23-ps pulses from a lamp-pumped Nd:YAG laser passively mode-locked by polarization switching in a KTP crystal

Autor: Vincent Couderc, Alain Barthélémy, B. Bourliaguet, Frédéric Louradour, Václav Kubeček

Publikováno v: Applied Physics B: Lasers and Optics. 69:99-102

Passive mode-locking of a cw lamp-pumped Nd:YAG laser using nonlinear polarization switching in a type-II SHG crystal is reported. Light pulses with more than 5 W of average power and pulse duration shorter than 25 ps have been obtained at 1064 nm.

Publikováno v: Optical and Quantum Electronics. 30:923-935

We present analytical, numerical and experimental results of the interactions between Type II vectorial spatial solitary waves (QSSW) in second-order non-linear media. We show that the outcome of the interaction can be changed from beam coalescence t

Proposal for a standoff bio-agent detection SWIR/MWIR differential scattering lidar

Autor: Michel Piché, Simon Lambert-Girard, Nicolas Hô, Paul-François Paradis, François Babin, B. Bourliaguet

Publikováno v: SPIE Proceedings.

A SWIR/MWIR spectroscopic lidar is proposed for standoff bio-agent cloud detection using simultaneous broadband differential scattering (DISC). Measurements and/or modeling of DISC spectra of simulants are revisited and the rational of the SWIR/MWIR

Hyperspectral fluorescence lifetime lidar for geological exploration

Autor: Nicolas Hô, Félix Cayer, Frédéric Émond, Francis Généreux, François Babin, B. Bourliaguet

Publikováno v: SPIE Proceedings.

We have developed a small, relatively lightweight and efficient lidar instrument for remotely detecting and classifying minerals. The system is based on a pulsed, eye-safe, diode pumped Nd:YAG laser, tripled (355nm) or quadrupled (266nm), for UV exci
