Laser source assembly with thermal control and mechanically stable mounting

摘要

A laser source (340) comprises a first frame (356), a laser (358), and a first mounting assembly (360). The laser (358) generates an output beam (354) that is directed along a beam axis (354A). The first mounting assembly (360) allows the laser (358) to expand and contract relative to the first frame (356) along a first axis and along a second axis that is orthogonal to the beam axis, while maintaining alignment of the output beam (354) so the beam axis (354A) is substantially coaxial with the first axis. The first mounting assembly (360) can include a first fastener assembly (366) that couples the laser (358) to the first frame (356), and a first alignment assembly (368) that maintains alignment of the laser (358) along a first alignment axis (370) that is substantially parallel to the first axis.

主权项

1. A laser source that generates an output beam that is directed along a beam axis that is coaxial with a first axis and orthogonal to a second axis, the laser source comprising:
a first frame; a laser that is adapted to generate the output beam that is directed along the beam axis, the laser including a second frame that includes a groove; and a first mounting assembly that couples the laser to the first frame, the first mounting assembly allowing the laser to expand and contract relative to the first frame along the first axis and along the second axis, while maintaining alignment of the output beam so the beam axis is substantially coaxial with the first axis; wherein the first mounting assembly includes a first fastener assembly that couples the laser to the first frame, and a first alignment assembly that maintains alignment of the laser along a first alignment axis that is substantially parallel to the first axis; wherein the first fastener assembly allows the second frame to expand and contract relative to the first frame along the first axis and along the second axis, while maintaining the approximate position of the second frame relative to the first frame along a third axis that is orthogonal to the first and second axes; wherein the first fastener assembly includes an engagement rod that fits into the groove and a resilient assembly that urges the engagement rod into the groove to urge the second frame toward the first frame.
