    Fully digital frequency stabilization of IR fiber-coupled laser

  • Original language description

    We present a stabilized semiconductor laser system designed to operate as a fiber-optic front-end master oscillator of a pulsed high-power iodine laser Prague Asterix Laser System _PALS_. The replacement of the PALS master oscillator is a part of a broader effort to rebuild PALS into a laser generating shorter pulses with higher pulse power by the technique of optical parametric chirped pulse amplification. With an operating wavelength of 1315.15 nm the stabilized laser master oscillator is based on a telecommunication single-frequency distributed feedback diode. The frequency stabilization is derived from transitions in thermally dissociated iodine. Locking to the selected transition is fully automatic and the control system employs a unique combination of control loops derived from temperature and absorption to overcome the problem of narrow locking range of a single absorption line.

    Digitální frekvenční stabilizace IR laseru vázaného do vlákna

  • Czech description

    Článek popisuje stabilizovaný polovodičový laser navržený jako řídicí oscilátor pro výkonový laserový systém PALS (Prague Asterix Laser System). Přechod na tento řídicí oscilátor umožní generování krátkých výkonových pulsů metodou OPCPA (Optical Parametric Chirped Pulse Amplification). Vzhledem k požadované vlnové délce 1315.15 nm bylo možno použít laserovou diodu pro telekomunikační účely. Tato je frekvenčně stabilizována na lineární absorpci v parách tepelně disociovaného jódu. Nalezení příslušné absorpční čáry je zcela automatické.
