Abstract
The carrier-envelope phase (CEP) of a laser pulse has been shown to influence many physical processes such as pulse propagation through polar molecules, cross-phase modulation, ponderomotive surface-plasmon electron acceleration, photoemission from metallic surfaces, terahertz emission from the laser breakdown of air, above-threshold ionization, high harmonic generation, and attosecond pulse generation. Current technology does not allow for the CEP stabilization of chirped pulse amplification (CPA) systems operating at a repetition rate much lower than a kHz. The inventors disclose apparatus and methods that enable CEP control in CPA systems operating at arbitrarily-low repetition rates.
