R. Danielius et al., TRANSFORMATION OF PULSE CHARACTERISTICS VIA CASCADED 2ND-ORDER EFFECTS IN AN OPTICAL PARAMETRIC-AMPLIFIER, Optics communications, 133(1-6), 1997, pp. 277-281
We have demonstrated the linear transformation of a pulse chirp throug
h second-order cascading in a degenerate phase-matched optical paramet
ric amplifier by means of the self-diffraction process. We have measur
ed as much as seven-fold enhancement of a frequency sweep rate in the
diffracted idler pulses with no visible onset of intensity-dependent e
ffects.
