Compact, single-frequency, doubly resonant optical parametric oscillator pumped in an achromatic phase-adapted double-pass geometry.
TL;DR: A compact source is demonstrated that provides pulsed, stable single-frequency output over a wide spectral range (3.8-4.3 μm) with a high peak power (up to 50 W), which are properties well suited for practical gas sensing applications.

High-resolution photoacoustic and direct absorption spectroscopy of main greenhouse gases by use of a pulsed entangled cavity doubly resonant OPO
TL;DR: In this article, an entangled cavity doubly resonant optical parametric oscillator (ECOPO) was developed to provide tunable narrow line width (<100 MHz) pulsed (8 ns) radiation over the 3.8-4.3μm spectral range at a multi-kilohertz repetition rate with up to 100-W peak power.

Specific architectures for optical parametric oscillators

TL;DR: Berrou et al. as mentioned in this paper showed that optical cavities can be specifically designed to increase either the optical conversion of the parametric process or to reduce dramatically the emitted line width, which is not encountered with usual laser sources.

TL;DR: By pumping a mid infrared entangled cavity doubly resonant optical parametric oscillator with a micro-laser, this paper demonstrated the full potentialities of this widely tunable source : high spectral purity, compactness and low threshold of oscillation.

TL;DR: In this paper, the authors demonstrate that output performance can be improved by using a partial pump beam reflection, which can be used to improve the performance of entangled cavity optical parametric oscillators for high resolution spectroscopy.
