Baum, P.; Riedle, Eberhard ; Greve, M. und Telle, Harald R. (August 2005): Phase-locked ultrashort pulse trains at separate and independently tunable wavelengths. In: Optics Letters, Bd. 30, Nr. 15: S. 2028-2030

Abstract

The generation and characterization of feratosecond pulses at three independently tunable visible wavelengths is reported. Selected spectral portions of a common continuum generated in sapphire are amplified in noncollinear optical parametric amplifiers. The phase relation of the pulse trains is analyzed with a nonlinear interferometer based on coherent anti-Stokes Raman scattering and is found to be locked to better than 250 mrad rms. Small spectral shifts of the pulses lead to interference behavior that is consistent with 1 kHz frequency combs. (c) 2005 Optical Society of America.
