Abstract
A thrust generating device according to the present invention is a thrust generating device for irradiating a target with a laser beam to generate thrust for the target, the thrust generating device including: a laser beam generating device that generates a first laser beam having a first wavelength and a second laser beam having a second wavelength different from the first wavelength; and an irradiation device that simultaneously irradiates the target with the first laser beam and the second laser beam. The second wavelength may be a wavelength having a high absorptivity in the target than the first wavelength, and the intensity of the second laser beam may be lower than that of the first laser beam. Further, the second laser beam may be generated by converting the wavelength of the first laser beam.
