Ultrabroad mid-infrared tunable Cr:ZnSe channel waveguide laser
Ultrabroad mid-infrared tunable Cr:ZnSe channel waveguide laser
Operation of a Cr:ZnSe external-cavity waveguide laser is demonstrated with a CW tuning range of 700 nm from 2077 to 2777 nm (36THz), the widest tuning range demonstrated by a waveguide laser. Narrow linewidths as low as 53 pm FWHM (3 GHz) are achieved and a maximum output power of 120 mW is attained at 2446 nm with over 15 mW available across the entire tunable range. A theoretical model is presented allowing the effect of changes to the system to be quantified in terms of laser performance, this allows the limitations of the architecture to be assessed. Good agreement is seen between the model and the experimental values obtained.

Abstract
Operation of a Cr:ZnSe external-cavity waveguide laser is demonstrated with a CW tuning range of 700 nm from 2077 to 2777 nm (36THz), the widest tuning range demonstrated by a waveguide laser. Narrow linewidths as low as 53 pm FWHM (3 GHz) are achieved and a maximum output power of 120 mW is attained at 2446 nm with over 15 mW available across the entire tunable range. A theoretical model is presented allowing the effect of changes to the system to be quantified in terms of laser performance, this allows the limitations of the architecture to be assessed. Good agreement is seen between the model and the experimental values obtained.
