  • Publication number: 20230049459
    Abstract: An assembly (10) for generating a laser beam (12) includes a beam steering assembly (18); a laser assembly (16) that is tunable over a tunable range; and a controller (20). The laser assembly (16) generates a laser beam (12) that is directed at the beam steering assembly (18). The controller (20) dynamically controls the beam steering assembly (18) to dynamically steer the laser beam (12) as the laser assembly (16) is tuned over at least a portion of the tunable range. As a result thereof, the laser beam (12) is actively steered along a desired beam path (12A) while the wavelength of the laser beam (12) is varied.
