29 W High power CW supercontinuum source.

A 29 W CW supercontinuum spanning from 1.06 to 1.67 microm is generated in a short length of PCF with two zero dispersion wavelengths. The continuum has the highest spectral power density, greater than 50 mW/nm up to 1.4 microm, reported to date. The use of a short length of PCF enables the continuum to expand beyond the water loss at 1.4 microm. The dynamics of the continuum evolution are studied experimentally and numerically with close attention given to the effects of the water loss and the second zero dispersion wavelength.
