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 ...
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 ...
