Tunable single-longitudinal-mode fiber optical parametric oscillator with saturable-absorber-based auto-tracking filter [PDF]

, 2010
A tunable single-longitudinal-mode (SLM) fiber optical parametric oscillator is demonstrated by using a subring cavity and a fiber loop mirror incorporated with a saturable absorber. It can provide dual-wavelength SLM output.

Single-longitudinal-mode diamond laser stabilization using polarization-dependent Raman gain [PDF]

, 2019
We report a novel cavity feedback mechanism for stabilizing single-longitudinal-mode (SLM) operation of diamond Raman lasers. Polarization-dependent Raman gain and in-grown stress birefringence in diamond were investigated as sources for Hänsch-Couillaud-
