Modulation Instability Induced Frequency Comb Generation in a Continuously Pumped Optical Parametric Oscillator
S. Mosca, M. Parisi, I. Ricciardi +7
Continuously pumped passive nonlinear cavities can be harnessed for the creation of novel optical frequency combs. While most research has focused on third-order "Kerr" nonlinear i…
Direct generation of optical frequency combs in nonlinear cavities
S. Mosca, I. Ricciardi, M. Parisi +4
Quadratic nonlinear processes are currently exploited for frequency comb transfer and extension from the visible and near infrared regions to other spectral ranges where direct com…
Walk-off-induced modulation instability, temporal pattern formation, and frequency comb generation in cavity-enhanced second-harmonic generation
F. Leo, T. Hansson, I. Ricciardi +4
We derive a time-domain mean-field equation to model the full temporal and spectral dynamics of light in singly resonant cavity-enhanced second-harmonic generation systems. We show…
Sub-kHz linewidth narrowing of a mid-infrared OPO idler frequency by direct cavity stabilization
I. Ricciardi, S. Mosca, M. Parisi +4
We stabilize the idler frequency of a singly-resonant optical parametric oscillator directly to the resonance of a mid-infrared Fabry-Pérot reference cavity. This is accomplished b…
Low-temperature spectroscopy of the CH () band in a helium buffer gas
L. Santamaria, V. Di Sarno, I. Ricciardi +5
Buffer gas cooling with a He gas is used to perform laser-absorption spectroscopy of the CH () band at cryogenic temperatures. Doppler thermometry is fi…
Frequency comb generation in quadratic nonlinear media
Iolanda Ricciardi, Simona Mosca, Maria Parisi +4
We experimentally demonstrate and theoretically explain the onset of optical frequency combs in a simple cavity-enhanced second-harmonic-generation system, exploiting second-order…
Room temperature GW bar detector with opto-mechanical readout
L. Conti, M. De Rosa, F. Marin +2
We present the full implementation of a room-temperature gravitational wave bar detector equipped with an opto-mechanical readout. The mechanical vibrations are read by a Fabry--Pe…
Experimental measurement of photothermal effect in Fabry-Perot cavities
M. De Rosa, L. Conti, M. Cerdonio +2
We report the experimental observation of the photothermal effect. The measurements are performed by modulating the laser power absorbed by the mirrors of two high-finesse Fabry-Pe…
