Coincidence detection of inharmonic pulses in a nonlinear crystal

Mostrar todas las versiones(2)

Two trains of light pulses at periods that are equally shifted from the harmonics of a missing fundamental are combined in a nonlinear crystal. As a result of a noncollinear phase-matched second-order nonlinear generation, a new train of pulses is obtained. When the temporal width of the input pulse...
