1 May 1990 Wavelength control of a diode laser for distance measuring interferometry
Author Affiliations +
A breadboard diode-laser-based distance-measuring interferometer which measures relative thsp1ement has been developed. A temperature-controlled Fabry-Perot etalon is used in a closed-loop system to lock the wavelength emitted by the diode laser source to one of its passbands. Experiments performed using a wavemeter and a commercial laser position transducer indicate that the locked wavelength is returned to the same absolute value to within 1 ppm (part per million) from turn-on to turn-on of the control system, and that the wavelength fluctuation is reduced to less than 0.1 ppm.
