Patent ID: 7379488

Claim:
A laser system, comprising: a laser pump structure including a multi-layer gain-structure adjacent to a dual-wavelength mirror-structure, said gain-structure including a plurality of first active layers and a plurality of second active layers spaced apart by barrier layers; a laser-resonator having a resonator axis, said laser-resonator formed between said mirror structure of said laser pump structure, and an external mirror structure spaced apart from said gain-structure; and a pump source arranged to deliver pump energy to said gain-structure for generating laser-radiation in said laser-resonator, wherein the first active layers are positioned at antinodes of a first standing wave of a first wavelength and second active layers are positioned at antinodes of a second standing wave of a second wavelength that is different from the first wavelength, wherein antinodes of the first standing wave and antinodes of the second standing wave located at different positions in the active layer, wherein the number of first active layers and the number of second active layers control the relative power output of light at each of the first and the second wavelengths; and wherein said first and second active layers each comprise a semiconductor material selected from the group consisting of In x Ga 1-x As y P 1-y , In x Ga 1-x As, Ga x In 1-x N y As 1-y and Ga 1-x As y Sb where 0.0<×x<1.0 and 0.0<y<1.0, x and y being independently selectable for each of the first and second active layers.
