We report on the direct generation of broadband mid-IR pulses from an optical parametric amplifier. Several crystals with extended IR transparency, when pumped at 800 nm, display a broad phase-matching bandwidth around 1 μm, allowing for the generation of idler pulses spanning the 3-5 μm wavelength range. Using LiIO3, we produce 2-μJ pulses tunable in the 3-4 μm range with bandwidth supporting 30-fs transform-limited duration.

Abstract

We report on the direct generation of broadband mid-IR pulses from an optical parametric amplifier. Several crystals with extended IR transparency, when pumped at 800 nm, display a broad phase-matching bandwidth around 1 μm, allowing for the generation of idler pulses spanning the 3-5 μm wavelength range. Using LiIO3, we produce 2-μJ pulses tunable in the 3-4 μm range with bandwidth supporting 30-fs transform-limited duration.
