Coherent electro-optical detection of terahertz radiation from an optical parametric oscillator.

چکیده
We report the realization of coherent electro-optical detection of nanosecond terahertz (THz) pulses from an optical parametric oscillator, which is pumped by a Q-switched nanosecond Nd:YVO4 laser at 1064 nm and emits at approximately 1.5 THz. The beam profile and wavefront of the THz beam at focus are electro-optically characterized toward the realization of a real-time THz camera. A peak dynamic range of approximately 37 dB/radical Hz is achieved with single-pixel detection.

A wideband coherent terahertz spectroscopy system using optical rectification and electro-optic sampling
We present a scheme for exploiting the nonresonant second-order nonlinearities in electro-optic media to extend the bandwidth of coherent spectroscopy in the far-infrared using ultrafast laser pulses.

متن کاملCoherent Excitation of Optical Phonons in GaAs by Broadband Terahertz Pulses
Coherent excitation and control of lattice motion by electromagnetic radiation in optical frequency range has been reported through variety of indirect interaction mechanisms with phonon modes. However, coherent phonon excitation by direct interaction of electromagnetic radiation and nuclei has not been demonstrated experimentally in terahertz (THz) frequency range mainly due to the lack of THz...
متن کاملGeneration of tunable continuous-wave terahertz radiation by photomixing the signal waves of a dual-crystal optical parametric oscillator
We present a continuous-wave dual-crystal optical parametric oscillator that generates signal waves of about 1.4μmwavelength with a tunable difference frequency 1ν between 0.64 and 5.3 THz. A model of the parametric gain in such a system indicates that the lowest reachable value for 1ν depends on the refractive index dispersion of the nonlinear material used. As a proof of principle, we demonst...
متن کاملTwo-dimensional imaging of continuous-wave terahertz radiation using electro-optic detection
We report the demonstration of two-dimensional electro-optic imaging using continuous-wave THz radiation. Two single-frequency laser diodes serve as the optical source for both the generation and detection processes. The generation process occurs by mixing in a photoconductive emitter, while the detection process utilizes an electro-optic crystal and charge coupled device camera. The method per...
متن کاملNanosecond terahertz optical parametric oscillator with a novel quasi phase matching scheme in lithium niobate.
We present an optical parametric oscillator pumped by a single mode Q-switched nanosecond Nd:YVO(4) laser for terahertz generation in periodically poled lithium niobate with a new phase matching scheme. This new method leads to an emission of terahertz radiation close to the Cherenkov angle and to a parallel propagation of the pump and signal wave. The emission frequency of this novel source is...
