An optical parametric generator with a cylindrical periodically poled LiNbO<sub>3</sub> crystal and a Nd:YAG commercial microchip pump laser yields continuous tuning of the emitted wavelengths over a broad spectral range (1.42–1.7 μm and 2.8–4.2 μm), with large efficiency, a high repetition rate, and low divergence, in a compact and stable device.
