Abstract
Adaptive holographic quantum-well films are high-sensitivity dynamic holographic media that can be used to self- compensate time-varying disturbances such as mechanical vibration in interferometers, laser speckle, fsec pulse broadening and arrival-time drift. The holograms are quasi- steady-state with a compensation bandwidth up to 1 MHz. Dispersion to all orders is compensated by forming a dynamic spectral-domain hologram of a signal pulse (that has a time- varying dispersion) referenced to a stable clock pulse. The hologram is read out using forward scattering phase conjugation to remove phase distortion to all orders, including linear order that induces drift in the time of flight. We also have used adaptive interferometry to combine two ultrashort pulses into a pulse train. The relative phase between the two pulses in the train are self-adaptively phase locked, and is immune to drifting optical path differences or delay times between the two input pulses.
