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.
