Abstract (en)
[origin: WO2023285483A1] The invention relates to a device (1) for generating at least one pulse in the mid-infrared, comprising an optical source (2) that emits at least one source pulse having a first spectral component of wavelength λ1 and a second spectral component of wavelength λ2, a non-linear crystal (3) configured to generate said at least one pulse at a wavelength λMIR in the mid-infrared via a difference-frequency-generation process, and a first optical parametric amplifier (5). According to the invention, the generating device (1) comprises at least one retarder (42) placed between the non-linear crystal (3) and the first optical parametric amplifier (5), the retarder (42) generating an optical delay suitable for synchronizing in the first optical parametric amplifier (5) said at least one pulse of wavelength λMIR with pump radiation at the first wavelength λ1 or at the second wavelength λ2.
