Abstract

We demonstrate efficient generation of a Raman-type optical frequency comb by employing adiabatic Raman excitation in an enhancement cavity. A broad frequency comb spanning over 130 THz is realized with an excitation power reduction exceeding three orders of magnitude compared with a single-pass configuration.
