ABSTRACT:
A method of enhancing wavelength tuning performance in an external cavity laser includes emitting light into the cavity of the laser at a range of angles relative to an optical axis of the cavity, and transforming emitted light of narrow beam divergence to light with beam divergence wider than the narrow beam divergence. The method further includes diffractively focusing the light of wider beam divergence.
