Optical Parametric Oscillation in Random Polycrystalline χ(2) Medium
2018 Edition, August 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We demonstrate the first OPO based on random phase matching. The OPO was based on ZnSe ceramic pumped by 62-fs, λ=2.35-μm Cr:ZnS laser pulses, had 90-mW pump threshold and produced an ultra-broad spectrum spanning 3-7.5 μm.

Internal optical parametric oscillation
1971 Edition, Volume 7, July 1, 1971 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The theory of optical parametric oscillation internal to the laser cavity is extended to include the dynamics of the population inversion of the laser medium, thus generalizing it to include all laser-oscillator systems. The equations of motion of the oscillator-laser...

Cascaded optical parametric oscillation
2003 Edition, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This work considers a cascaded optical parametric oscillator (OPO) in which photons at frequency are generated from a not-resonated pump field at frequency 4/spl omega/ by means of the two cascading down-conversion processes, the fields at frequencies 2/spl omega/ and...

Optical parametric oscillation with periodically poled stoichiometric lithium tantalate
2003 Edition, Volume 1, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A low-threshold (106-mW) singly resonant optical parametric oscillation (OPO) was demonstrated in near-stoichiometric periodically poled LiTaO/sub 3/. A simple oscillator, with a two-mirror cavity was pumped by a Nd:YVO/sub 4/ laser, had an output of 628 mW at 1.1 W pump...

Optical parametric oscillation in a vertical triple microcavity
2006 Edition, May 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report the first realization of a monolithic vertical-cavity, surface emitting micro optical parametric conversion nanostructure, triply resonant with the parametric frequencies, allowing parametric oscillation or amplification with a very low pump power...

Investigation of novel configuration of optical parametric oscillation based on oppositely-oriented crystal twins
2016 Edition, June 1, 2016 - Optical Society (The) (OSA)

We have investigated a novel configuration of optical parametric oscillation whereby signal twins and idler twins are simultaneously generated by both of two oppositely-oriented nonlinear crystals forming twins. Our theory is supported by our experiment.

Ultra-low threshold power on-chip optical parametric oscillation in AlGaAs-on-Insulator microresonator
2015 Edition, May 1, 2015 - Optical Society (The) (OSA)

We present a record-low threshold power of 7 mW at ~1.55 μm for on-chip optical parametric oscillation using a high quality factor micro-ring-resonator in a new nonlinear photonics platform: AlGaAs-on-insulator.

Cascaded optical parametric oscillation using a dual-grating PPLN crystal
2006 Edition, May 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We demonstrate tunable cascaded parametric oscillation in which the primary parametric oscillator signal internally pumps the secondary parametric oscillator. Above the secondary threshold we observe clamping of the primary signal, in accordance with theory.

High efficiency quasi-non-critical phase-matched KTiOPO 4 optical parametric oscillation
2011 Edition, May 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Quasi-non-critical phase-matched optical parametric oscillation has been achieved in periodically bonded KTiOPO 4 stack with a 1.064-μm pump laser. A slope efficiency of 65% has been measured for the total output power of signal and idler.

Group-velocity-matched noncollinear optical parametric oscillation in quasi-phase matched gratings
2007 Edition, May 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose a novel scheme of noncollinear phase matching for femtosecond optical parametric oscillation in periodically poled gratings. Consequently, the parametric gain is enhanced by orders of magnitude and the threshold for oscillation reduced...
