State Measurements with Short Laser Pulses and Lower-Efficiency Photon Detectors

Almut Beige, Gerhard C. Hegerfeldt

It has been proposed by Cook (Phys. Scr. T 21, 49 (1988)) to use a short probe laser pulse for state measurements of two-level systems. In previous work we have investigated to wha…
