Abstract
By recording low-pressure absorption lines of around , 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 with a low threshold of oscillation , is mode-hop-free tunable over , and displays single-frequency Fourier-transformed-limited operation (linewidth ). A high potential for nonlinear spectroscopy is also expected given the high peak power (70 W) and the good quality of the output beam.
