Abstract
Frequency divide-by-two (2:1) and divide-by-three (3:1) optical parametric oscillators (OPOs) are basic devices for the implementation of future accurate optical frequency division chains. We report our latest development toward a phase-locked 3:1 frequency division of a radiation at λp≈843 nm (355.9 THz), using doubly resonant oscillators (DROs) based on silver gallium sulfide (AgGaS2 or AGS) and multi-grating periodically poled lithium niobate (PPLN). The characteristics of both devices are reported. The major limitation to their practical phase-locking comes from the too weak output coupling efficiency of the idler-wave, with a maximum of 600 μW at 2.53 μm. Only ~25 pW of the second harmonic is generated, which avoids efficient beatnote detection
