High energy, ultrafast, wavelength-tunable fiber lasers using intra- and inter-pulse nonlinearities of higher order modes

The invention enables a new class of fibers that allow 10-100x higher energy operation than currently possible with fibers, and thus have demonstrated the highest peak power lasers directly out of a fiber (not needing any additional pulse compression components, which are usually lossy and alignment sensitive). In addition, the invention can also lead to discrete and large jumps inwavelength, which facilitates wide wavelength tuning ranges. The invention can address a critical market need with fiber lasers – an application space currently only accessible, in limited wavelength ranges, with bulk technology called OPOs.
