mid-infrared frequency comb generation and stabilization with few-cycle pulses
Alexander J. Lind, Abijith Kowligy, Henry Timmers +5
Mid-infrared laser frequency combs are compelling sources for precise and sensitive metrology with applications in molecular spectroscopy and spectro-imaging. The infrared atmosphe…
Infrared electric-field sampled frequency comb spectroscopy
Abijith S. Kowligy, Henry Timmers, Alex Lind +5
Molecular spectroscopy in the mid-infrared portion of the electromagnetic spectrum (3--25 um) has been a cornerstone interdisciplinary analytical technique widely adapted across th…
Tunable mid-infrared generation via wide-band four wave mixing in silicon nitride waveguides
Abijith Kowligy, Daniel Hickstein, Alex Lind +8
We experimentally demonstrate wide-band (>100 THz) frequency down-conversion of near-infrared (NIR) femtosecond-scale pulses from an Er:fiber laser to the mid-infrared (MIR) using…
Mid-infrared frequency comb generation via cascaded quadratic nonlinearities in quasi-phase-matched waveguides
Abijith S. Kowligy, Alex Lind, Daniel D. Hickstein +7
We experimentally demonstrate a simple configuration for mid-infrared (MIR) frequency comb generation in quasi-phase-matched lithium niobate waveguides using the cascaded-…
