Nonlinear vibrational spectrometer for bioapplications featuring narrowband 1-m pulses and a recycled OPA pump beam
Zsuzsanna Heiner, Valentin Petrov, Mark Mero
Moving the detection wavelength in vibrational sum-frequency generation (VSFG) spectroscopy to the near-infrared (> 700 nm) can potentially enable the study of molecular interfaces…

Efficient, sub-4-cycle, 1-μm-pumped optical parametric amplifier at 10 μm based on BaGa4S7
Zsuzsanna Heiner, Valentin Petrov, Mark Mero
We report on a μJ-scale mid-infrared optical parametric amplifier (OPA) based on the recently developed wide-bandgap orthorhombic crystal, BaGa4S7 (BGS), and directly compare its p…
