Abstract

Gas-filled anti-resonant hollow-core fiber (ARHCF) constitutes an efficient route towards development of high-energy fiber lasers in the near-infrared (NIR) and mid-infrared (MIR) spectral region. We will present our recent work on developing both vibrational and rotational Raman-active gas-filled fiber lasers spanning from the NIR up to around 4.3 μm wavelength. We will also show how such fiber lasers can be used for high-resolution photoacoustic gas sensing and imaging.
