Abstract

A Ti:sapphire-pumped idler-resonant femtosecond tandem optical parametric oscillator is reported that is based on periodically poled lithium niobate and operates with wavelength tuning from 2.1 to 4.2 µm (idlers) and 1.25 to 1.40 µm (signal). The configuration uses two cascaded gratings arranged so that the nonresonant signal from the first grating acts as a pump for the second grating. Novel phase-matching behavior is described and explained, including full tandem operation, degenerate parametric downconversion of the signal pulses, and simultaneous tandem operation with seeded optical parametric amplification. Signal spectra show characteristic depletion profiles, implying substantial conversion from the signal to the tandem idler output. © 2004 Optical Society of America.
