Abstract: Continuously tunable ultraviolet laser radiation at 397 nm was generated by doubling the output of a semiconductor diode laser. The fundamental radiation was provided by a 150 mW AlGaAs laser diode injected by a low-power AlGaAs laser diode which was frequency stabilized by optical feedback using a new scheme of a miniature external cavity. Second-harmonic generation was produced in a lithium-triborate crystal placed in a compact enhancement cavity. The fundamental radiation was used for sub-Doppler spectroscopy of the Ar I 4s(3)P degrees(0)-4p(1)P(1) transition at 795 nm; the second-harmonic radiation was used for spectroscopy of the Ca II 4(2)S(1/2)-4(2)P(1/2) transition at 397 nm.
