摘要: We report on two different optical parametric amplifier (OPA) schemes for the generation of few-optical-cycles pulses. Pulses with 180-THz bandwidth and 2-µJ energy are generated by a noncollinear OPA in visible; portion amplified pulse spectrum is compressed down to 7.2 fs using thin prism sequence. IR pulses tunable from 1.1 2.6 µm duration as short 14.5 achieved type-II pumped 780-nm, 18-fs hollow-fiber compressor.
