Simple method for mid-infrared optical frequency comb generation with dynamic offset frequency tuning
Mikhail Roiz, Krishna Kumar, Juho Karhu +1
We present a simple method for fully-stabilized mid-infrared optical frequency comb generation based on single-pass femtosecond optical parametric generation that is seeded by a co…
Photoacoustic characteristics of carbon-based infrared absorbers
Jussi Rossi, Juho Uotila, Sucheta Sharma +5
We present an experimental comparison of photoacoustic responsivities of common highly absorbing carbon-based materials. The comparison was carried out with parameters relevant for…
Experimental study of the effect of phase mismatch on a CW-pumped cascaded quadratic nonlinear frequency comb
Ville Ulvila, Markku Vainio
Optical frequency comb generation by continuous-wave-pumped cascaded quadratic nonlinearities (CQN) appears a promising alternative to well-established modelocked lasers, especiall…
High-resolution analysis of the band of radiocarbon methane
Santeri Larnimaa, Lauri Halonen, Juho Karhu +6
We present the first high-resolution measurements and rotational analysis of the fundamental asymmetric stretching vibrational band of radiocarbon methane. A spectrome…
