Simultaneously phase-matched blue and red light generation using BIBO

摘要

BiB_(3)O_(6) has been found to be simultaneously phase matchable for sum-frequency generation at 0.4627 and 0.6260 (mu)m by mixing the outputs of a 0.5321 (mu)m pumped parametric oscillator with the fundamental source at 1.0642 (mu)m. The simultaneous blue and red light generation is achieved under the temperature-insensitive phase-matching condition, and the relative strength of blue and red light can be controlled by changing the effective nonlinear constants through the azimuth angle. In addition, wide wavelength tuning of the simultaneous phase matching is obtained by the use of a noncollinear geometry, enabling a compact red-green-blue laser system based on the powerful solid-state laser.
