载波包络相位稳定

The electric field of a laser pulse can be described as a sinusoidal oscillation, called the carrier, multiplied by a slowly varying envelope function. When the pulse propagates through a medium, the relative position between the carrier wave and envelope may change due to chromatic dispersion and optical nonlinearities, causing a difference between phase velocity and group velocity. The carrier-envelope offset (CEO) phase, also known as the carrier-envelope phase (CEP), is defined as the difference between the optical phase of the carrier wave and the envelope position. The CEP determines the accuracy of high-energy and attosecond experiments and ultrafast spectroscopy measurements.

PHAROS lasers and FLINT oscillators can be equipped with feedback electronics for CEP stabilization of the output pulses. The CEO of the oscillators is actively locked to 1/4th of the repetition rate with a < 100 mrad standard deviation. The CEP drift occurring inside the amplifier and the user setup can be compensated with an out-of-loop f-2f interferometer, which is a part of the complete PHAROS active CEP stabilization package. Accordingly, CEP stabilization can also be achieved in complex OPCPA systems
