Abstract

There has been substantial recent interest in the generation of synchronized, tunable femtosecond pulses at two wavelengths. This has been demonstrated to date using various techniques such as a femtosecond optical parametric oscillator,¹ a mode-locked Ti:Al₂O₃/dye laser combination," and a novel optical sampling technique based on two mode-locked Ti:Al₂O₃ lasers,”' In this paper we describe anal ternative approach based on a single self-mode-locked⁴ Ti: Al₂O₃ laser system that simultaneously generated synchronized femtosecond pulses in two spectral bands.
