Abstract Backward wave oscillators represent a class of tunable sources of electromagnetic radiation that do not require a resonant cavity to satisfy the oscillation condition. In the optical regime, the Backward Wave Optical Parametric Oscillator (B

We report a self-phase-locked and degenerate backward wave optical parametric oscillator (BWOPO) generating a counterpropagating signal and an idler in the spectral band of optical communication. The device is based on a periodically poled Rb-doped K

Abstract Mirrorless optical parametric oscillators (MOPOs) are very attractive parametric devices that rely on the nonlinear interaction of counter-propagating photons to inherently establish distributed feedback, without the use of external mirrors

We present a differential absorption lidar (DIAL) laser transmitter concept designed around a Nested Cavity Optical Parametric Oscillator (NesCOPO) based Master Oscillator Power Amplifier (MOPA). The spectral bands are located around 2051 nm for CO2

We report on the development of a nanosecond mirrorless optical parametric oscillator (OPO) pumped at 1 μm. The gain medium of the OPO was periodically poled Rubidium-doped KTP with a grating period of Λ = 509 nm for the first order quasi-phase mat

We experimentally explored the design parameter space for periodically poled R b : K T i O P O 4 (PPRKTP) structures in type-II optical parametric oscillators (OPOs) pumped at 1.064 µm and operating in the 1.8–2.5 µm range. This study identifies

We observed backward-wave spontaneous parametric downconversion in sub-µm periodically poled Rb-doped KTP. Pumped at 800 nm, forward-wave signal at 1400 nm and backward-wave idler at 1868 nm were obtained.
