Abstract:
A laser comprising:first and second laser-resonators arranged such that a portion of the resonator axes of each are on a coaxial path;said first resonator including an OPS-structure arranged outside the coaxial path and having the composition of active layers thereof selected to provide a predetermined fundamental-wavelength of laser-radiation;an optical arrangement for delivering said pump-light to said gain-structure, thereby causing fundamental laser-radiation having said fundamental-wavelength to oscillate in said first laser-resonator;an optically-nonlinear crystal located in said coaxial path of said first and second laser-resonators and arranged for frequency-doubling said fundamental laser-radiation thereby providing frequency-doubled radiation having a wavelength half of said fundamental-wavelength; andsaid second laser-resonator arranged cooperative with said first resonator to cause said frequency-doubled radiation and said fundamental radiation to oscillate together along said coaxial path in a manner which causes amplification of said frequency doubled-radiation.
