Coherent Cherenkov radiation as an intense THz source
Diffraction and Cherenkov radiation of relativistic electrons from a dielectric target has been proposed as mechanism for production of intense terahertz (THz) radiation. The use of an extremely short high-energy electron beam of a 4th generation light source (X-ray free electron laser) appears to be very promising. A moderate power from the electron beam can be extracted and converted into THz...
متن کاملAll-fiber femtosecond Cherenkov radiation source.
An all-fiber femtosecond source of spectrally isolated Cherenkov radiation is reported, to the best of our knowledge, for the first time. Using a monolithic, self-starting femtosecond Yb-doped fiber laser as the pump source and the combination of photonic crystal fibers as the wave-conversion medium, we demonstrate milliwatt-level, stable, and tunable Cherenkov radiation at visible wavelengths ...
متن کاملControlling Cherenkov radiation with transformation-optical metamaterials.
In high energy physics, unknown particles are identified by determining their mass from the Cherenkov radiation cone that is emitted as they pass through the detector apparatus. However, at higher particle momentum, the angle of the Cherenkov cone saturates to a value independent of the mass of the generating particle, making it difficult to effectively distinguish between different particles. ...
متن کاملA Study on Narrow-band THz (Terahertz) Source with Adjustable Center Frequency Based on Optical Rectification
The center frequency of the narrow-band THz wave is always unstable with the optical rectification methods. Therefore, the high-phase stable time-delay generator Etalon and the parallel grating pair compressor with the self-adaptive optical path compensation function are designed according to the principle that two lasers in different paths will result in specific relative time delay; with LiNb...
متن کاملHigh-power source of THz radiation based on orientation-patterned GaAs pumped by a fiber laser.
We demonstrate a new source of frequency-tunable THz wave packets based on parametric down-conversion process in orientation-patterned GaAs (OP-GaAs) that produces muW-level THz average powers at the repetition rate of 100 MHz. The OP-GaAs crystal is pumped by a compact all-fiber femtosecond laser operating at the wavelength of 2 mum. Such combination of fiber laser and OP-GaAs technologies pro...
