A newly developed tunable YLF laser operating in the 2µm wavelength region demonstrates an output power of about 300 mW in a single longitudinal mode, combined with a high spectral purity. It has been employed for measurements of the first overtone spectrum of DCN in a molecular beam with bolometric detection, achieving a signal-to-noise ratio larger than 1000.
