Abstract
A tunable laser system where incoming light is separated into wavelength separated light; the separated light is focused into a plurality of single wavelength focal spots. The laser system includes a locally controllable reflectivity array having a plurality of individually controllable localized reflective elements corresponding to and reflecting one of the plurality of focal spots. A wavelength filter substantially allows wavelengths of the incoming light separated by a specified frequency to emerge as filtered light, while substantially barring other wavelengths. The separated light includes this filtered light. An elongation element for elongates the wavelength separated light into a plurality of elongated single wavelength focal spots. The locally controllable reflectivity array includes a plurality of sets of a plurality of individually controllable localized reflective elements, each set corresponding to and reflecting one of the elongated single wavelength focal spots.
