Mid-infrared frequency comb with 25 pJ threshold via CW-seeded optical parametric generation in nonlinear waveguide

Mikhail Roiz, Jui-Yu Lai, Juho Karhu +1

We demonstrate efficient generation of mid-infrared frequency combs based on continuous-wave-seeded femtosecond optical parametric generation in nonlinear waveguides. Conversion of…

Broadband photoacoustic spectroscopy of $^{14} CH_{4}$ with a high-power mid-infrared optical frequency comb

Juho Karhu, Teemu Tomberg, Francisco Senna Vieira +7

We report a photoacoustic spectroscopy setup with a high-power mid-infrared frequency comb as the light source. The setup is used in broadband spectroscopy of radiocarbon methane.…
