| 英文摘要 | A laser device comprising a pump source 10 operable to generate a pump beam 11 for a resonant cavity 74 in which a laser medium is arranged. A beam-shaping waveguide element 18 e.g. a fibre or rod is arranged between the pump source and the resonant cavity. Shaping of the pump beam is achieved by tailoring the refractive index profile of the waveguide element so that it yields an intensity distribution which spatially overlaps a desired ring-shaped Laguerre-Gaussian mode of the resonant cavity sufficiently well to achieve laser oscillation on said desired Laguerre-Gaussian mode. A ring-shaped or doughnut-shaped laser beam profile can thus be generated. The waveguiding element may have a capillary structure with an outer solid region having an inner region in the form of a hole. The inner region may be formed of micro-structured elements that form multiple holes. |
