摘要： A balanced optical-RF phase detector for the extraction of low-jitter radiofrequency (RF) signals from optical pulse trains is demonstrated. The extraction of the low-jitter radiofrequency signals is based on the precise phase detection by use of a differentially biased Sagnac-loop interferometer and synchronous detection. The phase-error signal from this balanced optical-RF phase detector, which is robust against drifts and photodetector nonlinearities, is used to regenerate low-jitter radiofrequency signals from optical pulse trains. Alternatively, the phase-error signal is used to generate a low-jitter optical pulse train, synchronized with a master radiofrequency signal or to synchronize multiple modelocked lasers with each other.

摘要： A RF-synchronization system includes a laser that creates pulse trains for synchronization. A modulation means transfers the timing information of the pulse train into an amplitude modulation of an optical or electronic system. A synchronization module changes the driving frequency of the modulation means until it reaches a phase-locked state with the pulse train.

摘要： A substantially dispersion-free optical filter cavity includes a first multilayer mirror and a second multilayer mirror, wherein each mirror includes layers of a less-refractive material and layers of a more-refractive material, the more-refractive material having a higher index of refraction than the less-refractive material. The mirrors are separated by a spacing, and the thickness of a plurality of the layers in the second multilayer mirror differ from corresponding layers in the first multilayer mirror to provide the cavity with complementary group-delay dispersion across the cavity with a phase difference within, e.g., ±0.015 rad across a range of wavelengths spanning at least, e.g., 50 nm.

摘要： The carrier-envelope phase in a train of optical pulses is varied utilizing the dispersive properties of lossless plates while the total dispersion in transmission is maintained practically constant. The plates include sloped surfaces and are mounted for displacement such that the ratio of the thicknesses of the two plates through which the optical pulses will pass can be varied by displacing the plates so as to shift the carrier-envelope phase in the optical pulses. In one embodiment, the plates include a barium fluoride wedge and a fumed silica wedge, wherein the wedges are bond together to form a composite structure with thicker and thinner portions of the wedges inversely matched.

摘要： Systems and methods for enhancing the stability of a mode-locked laser's output are disclosed. The laser systems include a mode-locking element that mode-locks the laser's output, and a semiconductor element. The semiconductor element produces a loss at the laser's operative wavelength that increases as pulse energy increases, thereby enhancing the stability of the mode-locked output. The semiconductor elements can be used to enhance stability of both passively and actively mode-locked laser systems.

摘要： Coherent electronic current, which can be used to generate coherent radiation, is generated by first generating and transmitting an array of discrete electron beamlets from a nanocathode array along a longitudinal axis. The array of electron beamlets is then focused to reduce the spacing that separates the electron beamlets. The transverse-axis spacing of the electron beamlets is then transferred to the longitudinal axis via an emittance exchange beamline, creating a periodically modulated distribution of coherent electronic current. The coherent electronic current can then be directed into a stream of photons to generate coherent radiation.
