Abstract
A dual-wavelength laser emitter is provided for emitting a dual-wavelength laser beam. The laser emitter includes a first laser beam source for generating a first laser beam having a first frequency and a second laser beam source for generating a second laser beam having a second frequency. A beam splitter is included for combining portions of the first and second laser beams to form a dual-wavelength laser beam. The dual-wavelength laser beam is then amplified via an amplifier. A stimulated Brillouin scattering cell may be included to phase conjugate the dual-wavelength laser beam to improve the quality of the output beam. A frequency-doubling crystal may further be included for doubling the frequency of the dual-wavelength laser beam. The dual-wavelength laser emitter then emits a laser output beam as a function of the frequencies and amplitudes of the first and second laser beams.
