✦ Synopsis
We report a compact nanosecond source based on optical parametric generation in a periodically-poled Lithium Niobate slab pumped with a Nd^3+^:YAG/Cr^4+^:YAG microchip laser at the wavelength 1.064 μm and capable of generating a diffraction-limited beam widely tunable through the mid-IR. The device efficiency is shown to reach 30% at relatively low (units of μJs) pump pulse energy and its spectrum to be narrowed down to 0.2 nm using low-power CW seed provided by a DFB laser.
