A. Boskovic et al., FEMTOSECOND FIGURE-OF-8 YB-ER FIBER LASER INCORPORATING A DISPERSION DECREASING FIBER, Electronics Letters, 31(17), 1995, pp. 1446-1448
A femtosecond figure of eight fibre laser has been constructed incorpo
rating a dispersion decreasing (tapered) fibre within the nonlinear lo
op to give rise to intensity (phase) dependent switching and adiabatic
compression. With system optimisation, it should be possible to achie
ve femtosecond operation without spectral sideband generation.
