  • Wavelet transform applied to internal defect detection by means of laser ultrasound 

    Mohamed Selim, Hossameldin; Piñal Moctezuma, Juan Fernando; Delgado Prieto, Miquel; Trull Silvestre, José Francisco; Romeral Martínez, José Luis; Cojocaru, Crina (2019-04-03)

    Laser-generated ultrasound represents an interesting nondestructive testing technique that is being investigated in the last years as performative alternative to classical ultrasonic-based approaches. The greatest difficulty ...
  • Strong-field-enhanced forward scattering of high-order harmonics 

    Serrat Jurado, Carles (Springer, 2015-01-25)
    Capítol de llibre
    Accés obert
    We show that scattering of ultrashort XUV pulses from strong-field driven electron wave packets is enhanced as compared with normal weak scattering from bound or free electrons. We predict large XUV amplification in ...
  • Chiral modes in 2D PT-symmetric nanostructures 

    Botey Cumella, Muriel; Herrero Simon, Ramon; Turduev, M.; Kurt, H.; Staliunas, Kestutis (Springer International Publishing, 2015-11-15)

    We propose the stabilization of the output beam of Broad Area Semiconductor (BAS) amplifiers through the introduction of a spatially periodic modulated potential. We show that a periodic modulation of the pump profile in ...

  • Multi-stability and transient chaotic dynamics in semiconductor lasers with time-delayed optical feedback 

    Zamora Munt, Jordi; Masoller Alonso, Cristina; García Ojalvo, Jordi (World Scientific Publishing, 2010)
    Capítol de llibre
    Accés restringit per política de l'editorial
    We investigate numerically the chaotic transient dynamics of a semiconductor laser with time-delayed optical feedback. This transient behavior is seen in the low-frequency fluctuations (LFF) regime ocurring when the laser ...
