Femtosecond 8.5 mu m source based on intrapulse difference-frequency generation of 2.1 mu m pulses
Original language description
We report on a femtosecond ∼8.5 μm, ∼2 μJ source based on the intrapulse difference-frequency generation (DFG) of 2.1 μm pulses in an AgGaSe2 (AGSe) crystal.Compared to the conventional ∼0.8 or 1 μm near-infrared (IR) pulses,a ∼2 μm driver for intrapulse DFG can provide more efficient conversion into the wavelengths longer than 5 μm due to a lower quantum defect and is more suitable for the non-oxide nonlinear crystals that have a relatively low bandgap energy. Using 26 fs, 2.1 μm pulses for type-II intrapulse DFG,we have generated intrinsically carrier-envelope phase-stable idler pulses with a conversion efficiency of 0.8%,which covers the wavelength range of 7–11 μm.Our simulation study shows that the blueshift of intrapulse DFG is assisted by self-phase modulation of the driving pulses in AGSe.The idler pulses are particularly useful for strong-field experiments in nanostructures,as well as for seeding parametric amplifiers in the long-wavelength IR.n
