Abstract
A simple external cavity diode laser (ECDL) in a Littrow configuration was established and actively frequency-stabilized by using a side-of-fringe stabilization technique. A wavelength tuning range of 60nm for the spectral range between 1000 and 1060nm was demonstrated by rotating the diffraction grating. A sub-kilohertz frequency stabilization of the ECDL was achieved. The linewidth of the laser was narrowed from 160kHz to 400Hz by laser frequency locking to a flank of a Fabry-Perot interferometer peak.
