    摘要： A laser source for use in providing a laser beam for industrial operations in an industrial plant. The laser source selectively providing a first laser beam at a first outlet having relatively high power and lower beam quality and a second laser beam at a second outlet having relatively lower power and higher beam quality. The laser source including an optical path selector device for selectively transmitting a first laser beam along a first or second optical line toward respective first and second outlets. The second optical path having an optical amplification unit for changing the first laser to the second laser. An industrial plant including at least a first laser source selectively controls the first laser source to provide the first and the second lasers to predetermined laser processing stations. A second laser source may be used and controlled to provide a first or second laser to an alternate laser processing station on a failure of another laser source.

    摘要： Embodiments of systems and methods are provided for a tunable laser device. The tunable laser device may include a diffraction grating connected to a pivot arm that pivots the diffraction grating about a pivot point to tune the laser device. In pivoting the diffraction grating about the pivot point, both the wavelength to which the diffraction grating is tuned and the length of the optical cavity may be changed. The length of the pivot arm may be selected to reduce the number of mode hops of the tunable laser device when tuning the laser device over its tuning range.

    摘要： A mirror structure is provided in which at least a portion of a wavefront sensor is integrated with a mirror. In particular, a mirror structure is provided in which a Hartmann mask or a microlens array of a Shack-Hartmann wavefront sensor is integrated with a mirror to provide a very compact wavefront detector/corrector in a single device. Such a mirror structure may be used with a tip-tilt stage in a laser cavity to provide much simplified adaptive optics in the cavity. Furthermore, a Hartmann Mask may be integrated with self deforming mirror comprising an active PZT layer bonded to a passive mirror substrate, wherein the Hartmann Mask comprises an array of apertures formed through the active PZT layer.

    摘要： An optical fibre laser or amplifier comprising an optical fibre and a pump radiation source configured to generate pump radiation which is received through an input end of the optical fibre. The optical fibre may include a doped core which is configured to guide the pump radiation and to generate or amplify and guide signal radiation when pump radiation passes through it. The optical fibre laser or amplifier may include a first reflector configured to reflect pump radiation and further comprises a second reflector configured to selectively reflect a portion of pump radiation. The selection of the portion of pump radiation to be reflected by the second reflector depends upon one or more of: the spatial position of the pump radiation, the direction of the pump radiation, and the polarisation of the pump radiation.
