摘要： A laser source (10) for emitting a set of sequential, different wavelength output beams (12) includes a gain medium (16), a feedback assembly (26) and a control system (30). The gain medium (16) includes a first facet (16A), and the gain medium (16) generates a beam (12A) that exits the first facet (16A). The feedback assembly (26) includes a feedback device (40) and a device mover (42). The feedback device (40) is positioned in the path of the beam (12A) that exits the first facet (16A) and the feedback device (40) redirects at least a portion of the beam (12A) back to the gain medium (16). The device mover (42) continuously adjusts an angle of incidence (θ) of the beam (12A) on the feedback device (40). The control system (30) selectively directs pulses of power to the gain medium (16) as the device mover (42) is continuously adjusting the angle of incidence (θ) of the beam (12A). Further, the laser source (10) can include a position detector (28) that generates a position signal that relates to the angle of incidence (θ) of the beam (12A) on the feedback device (40). In this embodiment, the control system (30) can selectively direct pulses of power to the gain medium (16) based on the position signal from the position detector (28). Further, the control system (30) can determine a center wavelength of the output beam (12) based on the position signal.

摘要： An optical illuminator assembly (10) for locating an object (20) in inclement conditions (22) includes a MIR laser source (12) having a semiconductor laser that directly emits (without frequency conversion) an output beam (16) that is in the MIR range, the output beam (16) being useful for locating the object (20). Additionally, the optical illuminator assembly (10) can include a MIR imager (14) that captures an image (18) of light in the MIR range near the object (20). Further, the MIR imager (14) can include an image display (26) that displays the captured image (18). In a first example, the MIR laser source (12) and the MIR imager (14) are spaced apart, and the image (18) captured by the MIR imager (14) includes the output beam (16) from the MIR laser source (12). With this design, a person (28) operating a vehicle (24) will be able to locate the object 20 in inclement conditions 22. In a second example, the MIR laser source (12) and the MIR imager (14) are positioned in close proximity to each other. In this example, the image (18) captured by the MIR imager (14) includes at least a portion of the object (20) illuminated by the output beam (16) from the MIR laser source (12).

摘要： In a semiconductor lasers using quantum well gain medium, a quantum well stack is mounted in an epi-down configuration. The epitaxial side of the device may be directly bonded to an efficient heat transport system so that heat may more easily leave the quantum well stack layers and be disposed at a heatsink. Such a device runs cooler and exhibits reduced loss mechanisms as represented by a laser system loss-line. External cavity systems using this configuration may permit a high degree of tunability, and these systems are particularly improved as the tuning range is extended by lowered cavity losses.
