摘要： A dye-laser includes a resonator formed between two mirrors. The resonator has a longitudinal Z-axis and transverse X- and Y-axes perpendicular to each other and perpendicular to the Z-axis. A beam of laser radiation circulates in the laser resonator generally in a path along the Z-axis. An optical arrangement is provided for expanding the circulating beam in the Y-axis in one circulation direction and correspondingly compressing the expanded beam in the opposite circulation direction. A diffraction grating having rulings parallel to an X-Z plane of the resonator is located in the resonator in the path of the Y-axis expanded beam. The resonator and the diffraction grating are configured and arranged such that the Y-axis expanded beam is incident on the diffraction grating at a compound angle, is diffracted by the diffraction grating onto one of the resonator mirrors, and is reflected by that mirror back onto the grating such that the circulating laser radiation is incident on the diffraction grating twice per round trip in the resonator.
