Monitoring ultrashort pulses by transverse frequency doubling of counterpropagating pulses in random media Academic Article uri icon


  • The authors study experimentally the transverse second-harmonic generation of counterpropagating pulses by a quasi-phase-matching in a medium with a random ferroelectric domain structure. The authors show that this parametric process results in a direct realization of the cross correlation of two optical signals and, therefore, it can be employed for direct characterizations of ultrashort pulses including their temporal structure and pulse front tilt. 2007 American Institute of Physics.
