Abstract
A fundamental laser beam is wavelength converted through nonlinear optical crystals by traveling in one direction, sequentially through two nonlinear optical crystals arranged in series. A wavelength-converted laser beam is generated and includes wavelength-converted laser beams having polarized directions differing from each other by angles in a range from 45° to 90°. The two nonlinear optical crystals have crystal orientation axes differing by 45° to 90° when viewed along the optical axis of the laser beam.
