Abstract
The first subpicosecond laser pulses were produced over a decade ago. Since then, steady progress in laser development has resulted in even shorter pulses, more reliable sources, and an increasingly wider range of wavelengths to choose from. Where laser pulses themselves are not short enough, nonlinear efforts in single-mode optical fibers can be used to compress, reshape, and frequency shift them further. Pulses have been generated that are as short as a few optical cycles in duration, are wavelength tunable, and have very high peak powers (although perhaps not all at the same time).
