We will develop a compact external cavity stabilization system, which will employ independent electro-optic control over the optical path length of the cavity and a wavelength-selective element. The system should be able to cover a 30 nm range and give mode-hop-free tuning over 20 nm intervals. The design of the feedback system will be compatible with any commercially available laser diode from 630 nm to 2 ?m including emerging 400 nm lasers. The feedback element is entirely electro-optic, compact and robust. In Phase 2 we will combine a commercially available laser diode at 1400 nm with our external cavity to produce a compact laser for water vapor spectroscopy.
