Paper Abstract

In this paper some results of a narrow-band tunable external- cavity semiconductor laser with the Littman set-up are reported. The laser system consists of a commercial semiconductor laser at wavelength of 803 nm, a blazed grating, and an external mirror. The output power 17.9 mW and sideband suppression ratio over 20 dB were obtained. The laser is tuned conveniently in a range greater than 10 nm. The laser is single frequency, has a narrow linewidth, and is tunable over a wide range. The laser beam has good directional stability when it is tuned.
