Abstract :
We have investigated the dependence of the linewidth of a grating-cavity laser on the fine-tuning of the grating dispersion curve relative to the external cavity modes. Variations on the order of 100 kHz were observed experimentally when tuning the laser frequency within one external cavity mode.
