Generation of multicycle terahertz pulses via optical rectification in periodically inverted GaAs structures
نویسندگان
چکیده
The authors demonstrate the generation of multicycle narrow-bandwidth terahertz pulses in periodically inverted GaAs structures using optical rectification of 2 m, 100 fs pump pulses. Three different types of orientation-inverted samples are employed: optically contacted multilayer, orientation-patterned, and diffusion-bonded GaAs. The terahertz pulses are characterized by two-color pump at 2 m and probe at 0.8 m terahertz time-domain spectroscopy and terahertz Michelson interferometry. © 2006 American Institute of Physics.

Generation of narrow-band terahertz radiation via optical rectification of femtosecond pulses in periodically poled lithium niobate
We demonstrate a promising technique for generating narrow-band terahertz electromagnetic radiation. Femtosecond optical pulses are propagated through a periodically poled lithium-niobate crystal, where the domain length is matched to the walk-off length between the optical and THz pulses. The bandwidth of the THz wave forms is 0.11 at 1.7 THz. Optical rectification gives rise to a THz wave for...
متن کاملOptical generation of narrow-band terahertz packets in periodically inverted electro-optic crystals: conversion efficiency and optimal laser pulse format.
We explore optical-to-terahertz conversion efficiencies which can be achieved with femto- and picosecond optical pulses in electro-optic crystals with periodically inverted sign of second-order susceptibility. Optimal crystal lengths, pulse durations, pulse formats and focusing are regarded. We show that for sufficiently short (femtosecond) optical pulses, with a pulsewidth much shorter than th...
متن کاملQuasi-half-cycle terahertz pulse generation via optical rectification in quantum wells using shaped optical pulses.
It is shown that optical rectification in biased quantum wells using specially shaped optical pulses can be used to generate quasi-half-cycle THz electromagnetic pulses. Namely, we investigate THz generation by pulses incorporating a rapid pi phase shift. We further explore the potential of this scheme for high-repetition-rate quasi-half-cycle THz pulse generation.
متن کاملTemperature dependence of narrow-band terahertz generation from periodically poled lithium niobate
Femtosecond optical pulses are used to generate narrow-band terahertz wave forms via optical rectification in a periodically poled lithium niobate crystal. By cooling the crystal to reduce losses due to phonon absorption, we are able to obtain bandwidths as narrow as 18 GHz at a carrier frequency of 1.8 THz. Temperature-dependent measurements show insignificant bandwidth broadening between 10 a...
متن کاملGeneration of tunable narrow-band surface-emitted terahertz radiation in periodically poled lithium niobate.
Generation of tunable narrow-band terahertz (THz) radiation perpendicular to the surface of periodically poled lithium niobate by optical rectification of femtosecond pulses is reported. The generated THz radiation can be tuned by use of different poling periods and different observation angles, limited only by the available bandwidth of the pump pulse. Typical bandwidths were 50-100 GHz, depen...
