Abstract

An external cavity laser (10) (and method of generating laser light) comprising: a laser light source (12); means for collimating light output by the laser light source (12); a diffraction grating (16) receiving collimated light; a cavity feedback mirror (18) reflecting light received from the diffraction grating (16) back to the diffraction grating (16); and means for reliably tuning the external cavity laser to discrete wavelengths.
