Birefringent photonic-crystal fibers provide efficient polarization-sensitive anti-Stokes frequency conversion of unamplified 35-fs Ti: sapphire laser pulses, giving rise to a doublet of intense blue-shifted emission spectral lines centered at 490 and 510 nm. We show that this anti-Stokes doublet can be wavelength-demultiplexed by a polarizationseparating prism. Generation of the 510-nm signal is decoupled from frequency conversion to 490 nm by accurately polarizing the pump field along one of the principal axes of the elliptically deformed fiber core.
