Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
(The Optical Society (OSA), 2013-08)
Different spatial distributions of optical vortices have been generated and characterized by implement- ing arrays of devil’s vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the ...
Multibeam second-harmonic generation by spatiotemporal shaping of femtosecond pulses
(Optical Society of America, 2012)
Experimental Demonstration of the Quasi-Direct Space-to-Time Pulse Shaping Principle
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
A new strategy of pulse shaping based on the
quasi-direct space-to-time (QDST) conversion principle has
been recently proposed theoretically [Mínguez-Vega et al., Opt.
Express 16, 16993 (2008)]. In this letter, the ...
Programmable quasi-direct space-to-time pulse shaper with active wavefront correction
(Optical Society of America, 2012)
We experimentally demonstrate an extremely compact and programmable pulse shaper composed of a single phase mask encoded into a spatial light modulator. Its principle of operation is similar to the previously theoretically ...
Synthesis of fractal light pulses by quasi-direct space-to-time pulse shaping
(Optical Society of America, 2012)
We demonstrated a simple diffractive method to map the self-similar structure shown in squared radial coordinate of any set of circularly symmetric fractal plates into self-similar light pulses in the corresponding temporal ...
Frequency resolved wavefront retrieval and dynamics of diffractive focused ultrashort pulses
(Optical Society of America, 2012-08)
In this work we demonstrate the ability of the spatiotemporal characterization technique STARFISH to retrieve the wavelength dependent wavefront of focused ultrashort laser pulses. The high resolution achievable with this ...
