Dual signal-wave optical parametric oscillatorusing periodically poled LiNbO ₃ with series gratings

Abstract

The authors present a dual signal-wave quasi-phase-matched optical parametric oscillator using periodically poled LiNbO3 with two grating periods. The wavelength separation of the signal waves was tuned from 2 to 22 nm by changing the grating periods and temperature in the 1.3 – 1.5 µm wavelength range.
