    • closedAccess   Controlled multi-beam supercontinuum generation in fused silica by means of spatial light modulators 

      Pérez Vizcaíno, Jorge; Carbonell Leal, Miguel; Buendia, Carlos D.; Tajahuerce, Enrique; Borrego Varillas, Rocío IEEE (2015-06)
      We report on deterministic femtosecond multi-filamentation in fused silica by encoding a diffractive microlens array into a spatial light modulator. The efficiency and focal length of each microlens are electronically ...

    • openAccess   Controlled Multibeam Supercontinuum Generation With a Spatial Light Modulator 

      Borrego Varillas, Rocío; Pérez Vizcaíno, Jorge; Mendoza-Yero, Omel; Mínguez-Vega, Gladys; Vázquez de Aldana, Javier R.; Lancis, Jesús IEEE (2014)
      We report on deterministic femtosecond multifilamentation in fused silica by encoding a diffractive microlens array into a spatial light modulator. The efficiency and focal length of each microlens are modified through ...

    • openAccess   Diffractive optics for spectral control of the supercontinuum generated in sapphire with femtosecond pulses 

      Romero, Carolina; Borrego Varillas, Rocío; Camino, Acner; Mínguez-Vega, Gladys; Mendoza-Yero, Omel; Hernández Toro, Juan; Vázquez de Aldana, Javier R. Optical Society of America (2011)
      We propose the use of kinoform diffractive lenses to focus near infrared femtosecond pulses in sapphire crystals for supercontinuum generation. It is shown that a strongly peaked structure appears in the blue region of the ...

    • openAccess   Dynamic Control of Interference Effects Between Optical Filaments through Programmable Optical Phase Modulation 

      Borrego Varillas, Rocío; Pérez Vizcaíno, Jorge; Mendoza-Yero, Omel; Vázquez de Aldana, Javier R.; Mínguez-Vega, Gladys; Lancis, Jesús IEEE (2016-06)
      Light beams shaped by programmable megapixel spatial light modulators (SLMs) are key to broadening the applications of photonics. In this paper, we consider the application of a SLM for the generation of two mutually ...

    • openAccess   Femtosecond filamentation in sapphire with diffractive lenses 

      Borrego Varillas, Rocío; Romero, Carolina; Mendoza-Yero, Omel; Mínguez-Vega, Gladys; Gallardo, I.; Vázquez de Aldana, Javier R. Optical Society of America (2013)
      In this paper, we demonstrate novel properties in the phenomenology of supercontinuum generation in sapphire with diffractive lenses and provide a complete spatial, spectral, and temporal characterization of the so-generated ...

    • openAccess   Frequency resolved wavefront retrieval and dynamics of diffractive focused ultrashort pulses 

      Alonso, Benjamín; Borrego Varillas, Rocío; Mendoza-Yero, Omel; Sola, Íñigo Juan; San Román, Julio; Mínguez-Vega, Gladys; Roso, Luis 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 ...

    • openAccess   On-axis non-linear effects with programmable Dammann lenses under femtosecond illumination 

      Pérez Vizcaíno, Jorge; Mendoza-Yero, Omel; Borrego Varillas, Rocío; Mínguez-Vega, Gladys; Vázquez de Aldana, Javier R.; Lancis, Jesús Optical Society of America (2013)
      We demonstrate the utilization of Dammann lenses codified onto a spatial light modulator (SLM) for triggering non-linear effects. With continuous wave illumination Dammann lenses are binary phase optical elements that ...
