Multi‐Watt Long‐Wavelength Infrared Femtosecond Lasers and Resonant Enamel Ablation

Abstract High average power broadband tunable long‐wavelength infrared (LWIR) femtosecond lasers operating at fingerprint wavelengths of 7–14 µm hold significant promise across a range of applications, including molecular hyperspectral imaging, strong‐field light‐matter interaction, and resonant tissue ablation. Here, a 6–12 µm broadband tunable parametric amplifier based on LiGaS 2 or …
