We report efficient noncollinear optical parametric amplification (NOPA) of ultrabroadband near-IR pulses tunable in the range at a repetition rate of . Improved generation of smooth near-IR continua (extending over ) at was achieved by weakly focusing of the driving laser beam into a sapphire plate with longer focal length lenses than previously reported. Using bulk potassium-titanyl phosphate () pumped at , powers as high as (14% pump conversion efficiency) and signal pulse durations as short as were obtained after a single white-light seeded NOPA stage.
