ABSTRACT:
An external cavity laser has a wavelength of the laser output that is tuned by a rotary tuning element mounted on the axle of a motor. The rotary tuning element includes a variable thickness interference film for wavelength selection, and a variable thickness compensation prism to adjust the cavity length appropriately for the selected wavelength, to stable wavelengths and mode-hop-free tuning ranges as the tuning element is rotated.
