Controlling the carrier-envelope phase of ultrashort light pulses with optical parametric amplifiers

Phys Rev Lett. 2002 Apr 1;88(13):133901. doi: 10.1103/PhysRevLett.88.133901. Epub 2002 Mar 18.


The phase link between signal, idler, and pump waves in a parametric interaction allows generation of an idler pulse with a phase independent of that of the input pulse. We suggest the use of a white-light seeded optical parametric amplifier as a self-stabilized source of few-cycle pulses, in which the phase of the electric field is exactly reproduced in each laser shot.
