Abstract
Mid-infrared (MIR) laser pulses ranging from 2 to 2.5 μm are generated from a single supercontinuum (SC) pulse by intra-pulse difference-frequency mixing (DFM) with a spectral focusing scheme (SF-DFM). By controlling the spectral phase of the SC pulse with a 4f-pulse shaper utilizing a liquid crystal spatial light modulator, SF-DFM enables us to vary the center wavelength, the bandwidth, and the pulse shape of MIR laser pulses, which are amplified by an optical parametric amplifier using a periodically poled LiNbO3 crystal.
