Pulse compression at an abrupt dispersive interface.
Reflection from the interface of a dielectric and a resonant medium we show can result in pulse narrowing and multiplication. Results are given for an asymmetric Fourier transform-limited pulse, and possible experimental situations are discussed. Using pulses from a colliding pulse mode-locking scheme, low-level pulses as short as 15 fsec may be achievable.
