Abstract

Operation of fibre lasers on individual higher order transverse modes has many attractions from a power scaling perspective. These include a higher threshold for unwanted nonlinear loss processes, reduced sensitivity to mode skew [1], as well as the prospect of improved energy extraction in pulsed systems. Moreover, it has also been shown that in some laser processing applications the use of doughnut-shaped beams or beams with a dynamically adaptable transverse profile can yield substantially higher processing speeds. However techniques for selecting individual higher order modes in multimode fibre oscillators are often quite difficult to implement and lack the flexibility to switch between modes to suit the application.
