Abstract

We experimentally evaluated a cadmium-telluride (CdTe) crystal as the nonlinear crystal for generation and detection of terahertz (THz) radiation by using a femtosecond-pulse laser. Numerical simulations based on the nonlinear Maxwell equations, including third-order optical dispersion within the spectral width of an optical pulse and absorption in the THz frequency region, well reproduce both the amplitude and phase spectra of the emitted THz wave. Excitation wavelength dependences of the THz radiation from the CdTe crystal indicate that the phase-matched condition is satisfied at a wavelength of 1000nm. We also experimentally demonstrated a THz generation and detection system using a 1045nm Yb-doped ultrashort-pulse fiber laser, and we verified that CdTe is one of the most suitable nonlinear crystals for a Yb-doped fiber laser.

FFT spectra (a), (b), and (c) and FFT phase (d), (e), and (f) generated from CdTe converted from Fig. 1. The wavelength of (a) and (d) is 945 nm , (b) and (e) is 1015 nm , and (c) and (f) is 1130 nm . Solid curves are experimental results and dashed curves are simulated ones. Under our experimental condition, absorption of water vapor in air is detected.

Fig. 3

Intensities of THz radiation from CdTe crystal for several pumping wavelengths (marked as open circles). These intensities are integrated with a Fourier amplitude spectrum from 0 to 4 THz calculated from the THz waveform. The dashed curve is the simulated result. Here, it is assumed that the THz wave is detected by EO sampling method using a ZnTe crystal and 800 nm sampling pulse.

Schematic for calculation of THz wave radiation. Induced nonlinear polarization at ( ρ cos θ , ρ sin θ , z ) excited by pump beam emits the differential frequency wave toward the r direction.

THz amplitude simulation comparing various damping parameters. The high-frequency region is growing so as to reduce damping. The center of the excitation wavelength is 1015 nm , and damping parameter is γ ω T = 0.0 , 0.04 , 0.088 , and 0.12.

THz generation and detection results excited Yb-doped fiber laser. THz generators used three kinds of crystals: GaAs , CdTe , and ZnTe . A THz detector uses CdTe as an EO crystal. The sample thickness of ZnTe and CdTe is 1 mm and that of GaAs is 0.5 mm . The spectral node causes the phase jump.
