Abstract

In this work we present a novel concept of compact broadband high resolution sum frequency generation spectroscopy system. Multiple channel picosecond fiber laser was used as a seed for narrowband (~1.5 cm^-1 ) and broadband ultrafast radiation sources. In order to achieve >500 cm^-1 linewidth widely tunable microjoule-level pulses in MIR spectral region (2 - 10 μm) broadband femtosecond source optimization was performed. Numerical simulations of various schemes with different nonlinear crystals and experimental results were presented and compared.
