(CTuD6) The Effect of Pump Coherence on the Efficient Generation of CW Pumped Supercontinuum

E. J. Kelleher; J. Travers; S. Popov; J. R. Taylor

ABSTRACT:We present results on the effect of pump bandwidth on the efficiency of generation of continuous-wave supercontinua. We show that the broadest supercontinuum is obtained for intermediate pump bandwidths in agreement with numerical modeling.

(CMK7) Nanotube-based passively mode-locked Raman laser.

C. E. Schmidt Castellani; E. J. Kelleher; J. C. Travers; D. Popa; Z. Sun; T. Hasan; A. C. Ferrari; S. Popov; J. R. Taylor

ABSTRACT: We demonstrate passive mode-locking of a Raman fiber laser using a nanotube-based saturable absorber. The normal dispersion cavity generates highly-chirped 500 ps pulses that are compressed down to 2 ps, with 1.4 kW peak power.

(JThB88) Non-Solitonic Extension of Supercontinua

B. H. Chapman; J. C. Travers; S. Popov; A. Mussot; A. Kudlinski; J. R. Taylor

ABSTRACT: Four wave mixing of solitons and dispersive waves can extend supercontinua into the long-wavelength normal dispersion region in double zero-dispersion wavelength fibers, where extension through soliton Raman-self-frequency-shift is denied.

(EA2) Nanotube-based passively mode-locked Ytterbium-pumped Raman laser

C. E. Schmidt Castellani, E. J. R. Kelleher, D. Popa, Z. Sun, T. Hasan, A. C. Ferrari, S. V. Popov and J. R. Taylor

ABSTRACT: We demonstrate passive mode-locking of a Raman fiber laser using a nanotube-based saturable absorber. The all-normal dispersion cavity pumped by an Ytterbium laser generates highly-chirper 340 ps pulses.
