Spatial-mode-demultiplexing for enhanced intensity and distance measurement
Luigi Santamaria, Deborah Pallotti, Mario Siciliani de Cumis +2
Spatial-mode demultiplexing (SPADE) has recently been adopted to measure the separation in the transverse plane between two incoherent point-like sources. It has been argued that t…
Laser induced fluorescence for axion dark matter detection: a feasibility study in YLiF:Er
C. Braggio, G. Carugno, F. Chiossi +8
We present a detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models. The…
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…
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…
