Tunable single-longitudinal-mode fiber optical parametric oscillator

open access: yesOptics Letters, 2010
A tunable single-longitudinal-mode (SLM) fiber optical parametric oscillator (FOPO) is proposed and demonstrated experimentally. A sub-ring cavity with a short cavity length is used to suppress the longitudinal modes and broaden the longitudinal mode spacing.
