A Tunable Cavity-Locked Diode Laser Source for Terahertz Photomixing
An all solid-state approach to the precise frequency synthesis and control of widely tunable terahertz radiation by differencing continuous-wave diode lasers at 850 nm is reported in this paper. The difference frequency is synthesized by three fiber-coupled external-cavity laser diodes. Two of the lasers are Pound–Drever–Hall locked to different orders of a Fabry–Perot (FP) cavity, and the thir...
متن کاملGeneration of widely tunable Fourier-transform-limited terahertz pulses using narrowband near-infrared laser radiation
Widely tunable, Fourier-transform-limited pulses of terahertz (THz) radiation have been generated using (i) crystals of the highly nonlinear organic salt 4-N ,N -dimethylamino-4-N -methyl stilbazolium tosylate (DAST), (ii) zinc telluride (ZnTe) crystals, (iii) gallium phosphide (GaP) crystals, and (iv) low-temperature-grown gallium arsenide (LTG-GaAs) photomixers with THz spiral antennas. Outpu...
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 کاملA High-power Frequency-stabilized Tunable Two-frequency Diode Laser System for Generation of Coherent Terahertz-wave by Photomixing
A tunable two-frequemcy high-power diode laser system at 850 nm for terahertz (Thz)wave generation by photomixing in lowtemperature-grown GaAs photo-conductors has been developed. The difference frequency is obtained through a three laser system, where two lasers are locked to different orders of a Fabry-Perot cavity and a third is offset-locked to the first, The difference-frequency signal is ...
متن کاملGeneration of tunable pulsed microwave radiation by nonlinear interaction of Nd:YAG laser radiation in GaP crystals.
Pulsed microwave radiation in a tuning range from 10 to 30 GHz has been generated through the parametric interaction of two near-infrared pulses in GaP crystals at low temperatures. The power of the microwave pulses (duration 30 nsec) was of the order of 1 mW. The pump pulses were generated with a Nd:YAG laser emitting simultaneously at two frequencies, within the bandwidth of the 1.064-microm ...
