Velocity distributions of sputtered excited atoms
(American Physical Society, 1982-02-08)
The first direct measurements are reported of the velocity distributions of sputtered atoms in excited states with electronic configurations completely different from the ground state. In contrast to previous work, the ...
Observation of the formation of the 0-pi pulse
(American Physical Society, 1984-08-06)
We have measured with 0.5-psec resolution the reshaping of small-area 7-psec laser pulses to 0-pi pulses due to their passage through an optically thick sodium cell. The reshaped pulses have a picosecond oscillatory structure ...
Measurement of the velocity distribution of sputtered Na atoms from NaCl by Doppler shift laser fluorescence
(AIP Publishing, 1981-11-01)
The velocity distribution of sputtered Na atoms from NaCI during 15 keV, Ar+ bombardment was measured by a Doppler shift laser fluorescence technique. Contrary to other measurements, the sputtered Na atoms were found to ...
Nonlinear picosecond-pulse propagation through optical fibers with positive group velocity dispersion
(American Physical Society, 1981-09-28)
The predictions of the nonlinear Schrodinger equation have been tested by passing 5.5-psec optical pulses through a 70-m single-mode optical fiber. With use of a precise cross correlation technique based on pulse compression, ...
Optical pulse compression based on enhanced frequency chirping
(AIP Publishing, 1982-07-01)
Through numerical simulations, we show that, under relatively general conditions, passage of an intense picosecond pulse through a single-mode optical fiber can cause the pulse to become strongly frequency broadened with ...
