Abstract
A grating-tuned cw dye laser with an emission bandwidth of less than 1 GHz and output power in excess of 400 mW has been constructed. This was accomplished using a newly developed holographic grating with sinusoidal groove profile, which resulted in an enhanced spectral efficiency up to 94%. The low losses and the broad spectral working range (more than 1000 Å) which can be easily covered by simple rotation make these gratings an attractive single-stage tuning element for low-gain cw lasers.
