Abstract
Solid state lasers emitting at first and a second wavelengths include an additional a conversion amplifier for converting photons having the first wavelength into photons having the second wavelength, thereby improving output efficiency of a preferred wavelength. Erbium lasing materials such as erbium doped garnets and fluorides, are employed, along with the conversion amplifier formed of a transition metal doped II-VI semiconductor, e.g., Cr:ZnSe.
