Broadband vibrational sum-frequency generation spectrometer at 100 kHz in the 950-1750 cm−1 spectral range utilizing a LiGaS2 optical parametric amplifier

Heiner, Zsuzsanna; Wang, Li; Petrov, Valentin; Mero, Mark

We present a 100 kHz broadband vibrational sum-frequency generation (VSFG) spectrometer operating in the 5.7-10.5 µm (950-1750 cm−1) wavelength range. The mid-infrared beam of the system is obtained from a collinear, type-I ...

Efficient generation of few-cycle pulses beyond 10 μm from an optical parametric amplifier pumped by a 1-µm laser system

Heiner, Zsuzsanna; Petrov, Valentin; Panyutin, Vladimir L.; Badikov, Valeriy V.; Kato, Kiyoshi; Miyata, Kentaro; Mero, Mark

Nonlinear vibrational spectroscopy profits from broadband sources emitting in the molecular fingerprint region. Yet, broadband lasers operating at wavelengths above 7 μm have been lacking, while traditional cascaded ...

Photoactive Yellow Protein Adsorption at Hydrated Polyethyleneimine and Poly-l-Glutamic Acid Interfaces

Krekic, Szilvia; Mero, Mark; Kuhl, Michel; Balasubramanian, Kannan; Dér, András; Heiner, Zsuzsanna

Chiral and achiral vibrational sum-frequency generation (VSFG) spectroscopy was performed in the 1400–1700 and 2800–3800 cm−1 range to study the interfacial structure of photoactive yellow protein (PYP) adsorbed on ...
