Pulse compression with large-mode-area photonic crystal fibres

Photonic crystal fibres (PCFs) are established tools for supercontinuum generation and femtosecond pulse compression down to the few-femtosecond regime. With the advent of femtosecond oscillators delivering ever higher pulse energy, one needs a pulse energy scalable technique to achieve these goals. Therefore, I will review the usage of large-mode-area PCFs for femtosecond applications and introduce some related new nonlinear fiber phenomena.
