Optical Pulse Squaring Effects in a Dispersive Delay Line.

摘要

Temporal squaring effects are produced using a pair of diffraction gratings on 30 psecduration 1.06 micrometer pulses that were negatively self phase modulated in cesium vapor. The results are in good agreement with the theory, which is discussed in detail. Further enhancement of the squaring by a saturable absorber is also discussed.
