Abstract
Wavelength conversion afforded by stimulated Raman scattering within a
hollow core fiber is potentially useful for multispectral light
detection and ranging (LiDAR). Herein, we make use of the ideal 1550
cm−1 vibrational Raman shift of an antiresonant
fiber filled with gaseous oxygen so that the first and second Raman
orders as well as the transmitted pump are all located in separate
atmospheric transmission windows. To the best of our knowledge, this
is the first report of stimulated Raman scattering in
an oxygen-filled fiber. The host of closely spaced rotational
stimulated Raman scattering (SRS) lines (12 cm−1)
accompanying the transmitted pump and vibrational Raman orders form
continuum bands allowing for much greater spectral coverage of the
atmospheric transmission windows. The temporal profiles of the Raman
orders can be separated without the use of a grating to potentially
achieve a multi-band LiDAR.
