Abstract
For at least partial fabrication of a mirror for an optical cavity, a surface to be processed of an optical substrate is positioned in an operating plane, which is equal to or parallel to a focal plane of a laser arrangement, and a concave surface profile of the surface is generated by applying a sequence of multiple laser shots to the surface by using a quantum cascade laser of the laser arrangement.
Claims15
A method for at least partial fabrication of a mirror for an optical cavity, the method comprising:
- positioning a surface to be processed of an optical substrate in an operating plane, which is identical to or parallel to a focal plane of a laser arrangement;
- and
- generating a concave surface profile of the surface by applying a sequence of multiple laser shots to the surface by using a quantum cascade laser of the laser arrangement.
A fabrication arrangement for at least partial fabrication of a mirror for an optical cavity, the fabrication arrangement comprising:
- a laser arrangement comprising a quantum cascade laser;
- a positioner device with a holder for taking up an optical substrate to be processed, and configured to move the optical substrate relative to the laser arrangement;
- and
- at least one control unit configured to control the positioner device to position a surface to be processed of the optical substrate in an operating plane, which is identical to or parallel to a focal plane of the laser arrangement, and to control the quantum cascade laser to apply a sequence of multiple laser shots to the surface to generate a concave surface profile of the surface.
