Abstract

By recording low-pressure absorption lines of N<sub>2</sub>O around 3.9 μm, we fully qualify a pulsed entangled-cavity doubly resonant optical parametric oscillator as a power tool for high-resolution spectroscopy. This compact source runs at a high repetition rate (>10 kHz) with a low threshold of oscillation (<8 μJ), is mode-hop-free tunable over 5 cm <sup>-1</sup>, and displays single-frequency Fourier-transformed-limited operation (linewidth <0.005 cm<sup>-1</sup>). A high potential for nonlinear spectroscopy is also expected given the high peak power (70 W) and the good quality (<i>M</i><sup>2</sup><2) of the output beam.
