Paper Abstract

We present a fully digital stabilized semiconductor laser system designed to operate as a fiber-optic front-end o a pulsed power laser PALS (Prague Asterix Laser System). With an operating wavelength of 1315.15 nm the stabilized laser is based on a telecommunication single-frequency DFB (Distributed FeedBack) diode. The lines are detected by means of linear absorption in a heated cell filled with thermally dissociated iodine. The detection scheme is based on a derivative spectroscopy with a current frequency modulation and thermal wavelength control. The detection chain together with stabilization servo loop is fully digital represented by signal-processing single-chip controllers. The operation of the controllers can be monitored by PC via CAN (Control Area Network) bus. The algorithm of the absorption spectrum scanning, line selection and locking makes it possible to operate the laser in a maintenance-free regime, monitored only by a "ready" signal from a control panel of the PALS.
