We compensate the spectral phase using a set of chirped mirrors with total group delay dispersion of ~-300 fs2 and third order dispersion of ~-290 fs3. We measure the compressed intensity and phase of the pulse using a single-shot FROG capable of m ...

... When data rates were in the low gigabit range and transmission distances were less than 100 km or so, most fiber optic transmitters used directly modulated lasers. However, as data rates and span lengths grew, waveguide chirp, caused by turning a laser on and off, limited data rates. Dispersion prob ...

... atoms are excited to the 4s4p level using a nsec dye laser. A 500 fsec, 392 nm laser pulse then drives the 4s4p - 4snd transition producing a Rydberg wavepacket centered near n = 25. A second, identical 392 nm pulse enters the laser/atom interaction region nearly co-linearly with the first psec pulse ...
