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 ... -
Diffraction-Based Phase Calibration of Spatial Light Modulators With Binary Phase Fresnel Lenses
Mendoza-Yero, Omel; Mínguez-Vega, Gladys; Martínez-León, Lluís; Carbonell Leal, Miguel; Fernández Alonso, Mercedes; Doñate-Buendía, Carlos; Pérez Vizcaíno, Jorge; Lancis, Jesús IEEE (2016)We propose a simple and robust method to determine the calibration function of phase-only spatial light modulators (SLMs). The proposed method is based on the codification of binary phase Fresnel lenses (BPFLs) onto an ... -
Diffractive control of 3D multifilamentation in fused silica with micrometric resolution
Mendoza-Yero, Omel; Carbonell Leal, Miguel; Doñate-Buendía, Carlos; Mínguez-Vega, Gladys; Lancis, Jesús Optical Society of America (2016)We show that a simple diffractive phase element (DPE) can be used to manipulate at will the positions and energy of multiple filaments generated in fused silica under femtosecond pulsed illumination. The method allows ... -
Effects of mitigation of pixel crosstalk in the encoding of complex fields using the double-phase method
Carbonell Leal, Miguel; Mendoza-Yero, Omel Society of Photo-optical Instrumentation Engineers (2020)We report on unwanted effects of pixel cross-talk and its mitigation on the experimental realization of the double-phase method with phase-only spatial light modulators. We experimentally demonstrate that a generalized ... -
Encoding of arbitrary micrometric complex illumination patterns with reduced speckle
Carbonell Leal, Miguel; Mínguez-Vega, Gladys; Lancis, Jesús; Mendoza-Yero, Omel Optical Society of America (2019)In nonlinear microscopy, phase-only spatial light modulators (SLMs) allow achieving simultaneous two-photon excitation and fluorescence emission from specific regionof-interests (ROIs). However, as iterative Fourier ... -
Generation of multifocal irradiance patterns by using complex Fresnel holograms
Mendoza-Yero, Omel; Carbonell Leal, Miguel; Mínguez-Vega, Gladys; Lancis, Jesús Optical Society of America (2018)We experimentally demonstrate Fresnel holograms able to produce multifocal irradiance patterns with micrometric spatial resolution. These holograms are assessed from the coherent sum of multiple Fresnel lenses. The utilized ... -
Second-harmonic illumination to enhance multispectral digital lensless holographic microscopy
Mendoza-Yero, Omel; Carbonell Leal, Miguel; Lancis, Jesús; García Sucerquia, Jorge Optical Society of America (2016-03)Multispectral digital lensless holographic microscopy (MDLHM) operating with second-harmonic illumination is shown. Added to the improvement of the spatial resolution of the previously reported MDLHM operating with ... -
Shaping the Amplitude and Phase of Laser Beams by Using a Phase-only Spatial Light Modulator
Carbonell Leal, Miguel; Mendoza-Yero, Omel Journal of Visualized Experiments (2019-01-29)The aim of this article is to visually demonstrate the utilization of an interferometric method for encoding complex fields associated with coherent laser radiation. The method is based on the coherent sum of two uniform ... -
