A single-mode GaAlAs diode laser with over 90% output-coupling power and a large frequency-scanning range is reported. Based on grating feedback in the Littrow configuration, it is demonstrated that, with weak feedback (1.5 × 10−3 in this experiment), over a 7.5-GHz continuous tuning range can be achieved around tuning gaps of free-running operation. A frequency self-locking effect is also demonstrated in this system.

  10. For the 5-cm confocal interferometer used in our experiment, the linewidth is measured to be approximately 7.5 MHz. The Littrow angle θL ≈ 44.6° for 780 nm, together with a measured beam size on the grating surface of approximately 1.5 mm and the grating constant of 1800 mm−1, we get a dispersive FWHM of the grating around 33 GHz.
