Enhancing red-shifted white-light continuum generation in optical fibers for applications in nonlinear Raman microscopy.

We report an efficient red-shifted continuum generation of picosecond pulses in conventional optical fibers. By using a novel highrepetition rate, high-energy oscillator operating at the fundamental wavelength of 1064 nm, we achieved more than 60% of the output energy in the spectral range from 1150 to 1300 nm, perfectly suitable for broadband coherent anti-Stokes Raman spectroscopy.
