ABSTRACT:
A multiple wavelength operating laser (10) having a pump cavity or enclosure (14) surrounded by an optical pumping arrangement (17) comprises a plurality of substantially concentric tubes (21A, 21B) each having windows for emission of radiation and enclosing respective bodies of liquid lasing media. The lasing media may be flowed through the respective tubes and are preferentially arranged so that the fluorescence spectra of the lasing medium in one tube overlaps the absorption spectra of the lasing medium in the adjoining tube so that the one lasing medium optically pumps the other lasing medium in addition to optical pumping from the optical pumping arrangement (17).
