  • Abstract
    The first demonstration, to the best of our knowledge, of continuous-wave (cw) difference-frequency generation in LiInS2 crystal is reported. Two Ar+ laser-pumped Ti:sapphire lasers were employed as widely tunable pump sources. With a total input power intensity of ∼5 kW/cm2, DFG power of 33.5 nW was produced at 7 μm, which yielded a power conversion efficiency of about 1 μW/(W2.cm), and an estimated effective nonlinear coefficient deff of 4.17 pm/V.
