Actively controlled tuning of an external cavity diode laser by polarization spectroscopy

Opt Express. 2009 Mar 30;17(7):4991-6. doi: 10.1364/oe.17.004991.

Abstract

We report on an universal method to achieve and sustain a large mode-hop free tuning range of an external cavity diode laser. By locking one of the resonators using a closed loop control based on polarization spectroscopy while tuning the laser we achieved mode-hop free tuning of up to 130 GHz with a non AR-coated, off-the-shelf laser diode.
