Abstract:
A medium for converting a pump wavelength of a pump laser to at least one desired output wavelength different from the pump wavelength, the medium comprising:a doped layer which is impregnated with at least one type of laser dye; a first undoped layer which is not impregnated with laser dye; a second undoped layer which is not impregnated with laser dye; an input optical coating disposed on a surface of the first undoped layer; and an output optical coating disposed on a surface of the second undoped layer, wherein: the input optical coating and the output optical coating are configured to form an optical resonator within the medium; and the output optical coating is partially reflective at a desired output wavelength and highly reflective at the pump wavelength; and encoding means for encoding said at least one desired output wavelength onto said medium.
