Journal ArticleDOI
Broadband Coherent Raman Scattering Microscopy
TL;DR: In this article, the current state of the art in broadband CRS microscopy is reviewed, both in the coherent anti-Stokes Raman scattering (CARS) and the stimulated Rambus scattering (SRS) versions.
Journal ArticleDOI
Fiber-format stimulated-Raman-scattering microscopy from a single laser oscillator
Alessio Gambetta,Vikas Kumar,Giulia Grancini,Dario Polli,Roberta Ramponi,Giulio Cerullo,Marco Marangoni +6 more
TL;DR: A highly simplified architecture for stimulated-Raman-scattering microscopy is demonstrated, where multiple tunable narrowband picosecond pulses are generated by spectral compression of femtosecond pulse emitted by a single compact Er-fiber oscillator.
Journal ArticleDOI
Transient Optical Response of a Single Gold Nanoantenna: The Role of Plasmon Detuning
Margherita Zavelani-Rossi,Dario Polli,Serguei Kochtcheev,Anne-Laure Baudrion,Jérémie Béal,Vikas Kumar,Egle Molotokaite,Marco Marangoni,Stefano Longhi,Giulio Cerullo,Pierre-Michel Adam,Giuseppe Della Valle +11 more
TL;DR: In this article, femtosecond pump-probe microscopy was used to study the transient plasmonic response of individual gold nanoantennas fabricated by electron-beam lithography on a glass substrate.
Journal ArticleDOI
Fiber-format CARS spectroscopy by spectral compression of femtosecond pulses from a single laser oscillator
Marco Marangoni,Alessio Gambetta,Cristian Manzoni,Vikas Kumar,Roberta Ramponi,Giulio Cerullo +5 more
TL;DR: An approach to coherent anti-Stokes Raman scattering (CARS) spectroscopy/microscopy based on spectral compression of femtosecond pulses emitted by a compact Er-fiber oscillator is demonstrated.
Journal ArticleDOI
Broadband stimulated Raman scattering with Fourier-transform detection.
Julien Réhault,Francesco Crisafi,Vikas Kumar,Gustavo Ciardi,Marco Marangoni,Giulio Cerullo,Dario Polli +6 more
TL;DR: A new approach to broadband Stimulated Raman Scattering (SRS) spectroscopy and microscopy based on time-domain Fourier transform (FT) detection of the stimulated Raman gain (SRG) spectrum is proposed.
