| 英文摘要 | An apparatus for controlling the spatial beam profile (1) of laser radiation (2), which apparatus comprises a laser (3) and a resonant fibre (4), wherein: the laser (3) is connected to the resonant fibre (4); the resonant fibre (4) comprises a first core (5), a cladding (6) and a waveguide structure (7); the first core (5) supports a fundamental mode (8) at a first wavelength (9) and at a second wavelength (10); the waveguide structure (7) supports a mode (13) at the first wavelength (9) and at the second wavelength (10); the waveguide structure (7) is positioned such that the fundamental mode (8) supported by the first core (5) overlaps the waveguide structure (7) at the first wavelength (9); the waveguide structure (7) is such that the fundamental mode (8) couples between the first core (5) and the waveguide structure (7) at the first wavelength (9); the resonant fibre 4 is defined by a length (11); the length (11) is such that the proportion of the laser radiation (2) that is emitted from the first core (5) compared to the laser radiation (2) emitted from the waveguide structure (7) is different at the first wavelength (9) compared to the second wavelength (10); the spatial beam profile (1) of the laser radiation (2) is determined by the proportion of the laser radiation (2) that is emitted from the first core (5); the laser (3) is selected such that its output wavelength (12) is able to be changed from the first wavelength (9) to the second wavelength (10), thereby enabling the spatial beam profile (1) to be controlled. |
