Abstract
A laser source (10) for emitting an output beam (12) includes a first gain medium (16B) that generates a first beam (16A), a second gain medium (18B) that generates a second beam (18A), a common feedback assembly (28) positioned in the path of the first beam (16A) and the second beam (18), and a control system (32). The common feedback assembly (28) redirects at least a portion of the first beam (16A) back to the first gain medium (16B), and at least a portion of the second beam (18A) back to the second gain medium (18B). The control system (32) selectively and individually directs power to the first gain medium (16B) and the second gain medium (18). Additionally, the common feedback assembly (28) can include a feedback mover (46) that continuously adjusts the angle of incidence of the first beam (16A) and the second beam (18A) on the feedback assembly (28). Moreover, the control system (32) can selectively direct pulses of power to the gain mediums (16B) (18B) based on the position of the feedback assembly (28).
