Ultrabroadband self-phase-stabilized pulses by difference-frequency generation.
Ultrabroadband near-IR (800-1700-nm) pulses are obtained by type II difference-frequency generation (DFG) between two synchronized noncollinear optical parametric amplifiers. Self-stabilization of the carrier-envelope offset phase, as expected from the DFG process, is demonstrated experimentally.
