M. Cavallari et al., MID-INFRARED FEMTOSECOND PULSE GENERATION BY WAVE-MIXING - NUMERICAL-SIMULATION AND EXPERIMENT, Optics communications, 114(3-4), 1995, pp. 329-332
Numerical simulations of the parametric difference-frequency-mixing pr
ocess in the femtosecond regime are presented. The calculations indica
te that sub-100 fs pulses may be produced in the 3 to 5 mu m range usi
ng available sources. Theoretical results are compared to experiments
on asynchronous frequency-mixing of two femtosecond Ti:sapphire lasers
.
