Mosley, P. J., Huang, W. C., Welch, M. G., Mangan, B. J., Wadsworth, W. J. and Knight, J. C., 2010. Ultrashort pulse compression and delivery in a hollow-core photonic crystal fiber at 540 nm wavelength. Optics Letters, 35 (21), pp. 3589-3591.
We have fabricated a bandgap-guiding hollow-core photonic crystal fiber (PCF) capable of transmitting and compressing ultrashort pulses in the green spectral region around 532 nm. When propagating subpicosecond pulses through 1 m of this fiber, we have observed soliton-effect temporal compression by up to a factor of 3 to around 100 fs. This reduces the wavelength at which soliton effects have been observed in hollow-core PCF by over 200 nm. We have used the pulses delivered at the output of the fiber to machine micrometer-scale features in copper.
