Continuously tunable ultraviolet laser radiation at 397 nm was generated by doubling the output of a semiconductor diode laser.

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 0 0−4p 1 P 1 transition at 795 nm; the second-harmonic radiation was used for spectroscopy of the Ca II 42 S 1/2−42 P 1/2 transition at 397 nm.File | Dimensione | Formato | |
