- Аннотация: We report on a first of its kind broadband amplification in the Fe:CdSe single crystal in mid-IR beyond 5 μm. The experimentally measured gain properties demonstrate saturation fluence close to 13 mJ/cm^2 and support the bandwidth up to 320 nm (full width at half maximum). Such properties allow to push the the energy of seeding mid-IR laser pulse, generated by optical parametric amplifier, up to more than 1 mJ. Dispersion management with bulk stretcher and prism compressor enables 5-μm laser pulses of 134 fs duration, providing the access to multigigawatt peak power. Ultrafast laser amplifiers based on family of Fe-doped chalcogenides open the route for wavelength tuning together with energy scaling of mid-IR laser pulses that are strongly demanded for the areas of spectroscopy, laser-matter interaction and attoscience.
