FIG. 1.

Waveguide design. (a) Bulk Cr2+:ZnSe crystal with buried channel waveguides. (b) Detailed view of the double depressed cladding waveguide cross-section. Red regions represent a region subject to higher irradiances than orange regions. White coloured core is a non-irradiated Cr:ZnSe region now surrounded by reduced index cladding.

FIG. 2.

Pump and signal waveguide modes. (a) Image of the 1928 nm waveguide mode. (b) Image of the 3392 nm waveguide mode, showing wavelengths beyond the emission band of Cr2+:ZnSe are also guided by the structure. The field of view for both (a) and (b) is 60 μm horizontal, 50 μm vertical. (c) Image of the 2500 nm waveguide mode. (d) Image of the 2500 nm light propagating through unmodified material under the same optical alignment as (c).

Waveguide laser characterisation studies. (a) Waveguide laser cavity assembly with butt-coupled dichroic mirror and output coupler mirror. (b) Laser output power against input pump power. (c) Near field image of the laser output mode at 2573 nm. (d) Laser output power spectral density.
