چکیده

A phase-locked coaxial transit time oscillator is designed for microwave sources with a small volume and low magnetic field in high-power coherent combining. The achieves controlled output phase through pre-modulation of electron beams. To improve the performance fields, reentrant input cavity used to ensure stability uniformity electric field. Electric buncher extractor also improved. reduce device volume, reflector function axial size device. Particle-in-cell simulation shows that 5 kW power sufficient lock-in 610 MW microwave, conversion efficiency 40.6% at 0.66 T. ratio reaches −50.8 dB. Simulation results demonstrate can still achieve locking as 0.5

Low-Temperature QED with External Magnetic Field

Low-temperature expansion of the effective Lagrangian of the QED3+1 with a uniform magnetic field and a finite chemical potential is performed. Temperature corrections, as well as zero-temperature expression for the effective Lagrangian are presented as finite sums over partially filled Landau levels. † E-mail address: [email protected]

Towards an Integrated Optic Phase-locked Oscillator

A recent experiment, performed at the Massachusetts Institute of Technology, has demonstrated that by locking a microwave oscillator to an optical pulse train from a modelocked laser, exceptional timing stability can be achieved. In the experiment, a 10.225-GHz microwave oscillator was locked to an optical phase detection apparatus consisting of a modelocked laser, a Sagnac interferometer, and ...

A phase-locked frequency divide-by-3 optical parametric oscillator

Accurate phase-locked 3:1 division of an optical frequency was achieved, by using a continuous-wave (cw) doubly resonant optical parametric oscillator. A fractional frequency stability of 2×10-17 of the division process has been achieved for 100 s integration time. The technique developed in this work can be generalized to the accurate phase and frequency control of any cw optical parametric os...
