Abstract

We report on the generation of impulsive terahertz (THz) radiation with 36 kV/cm vacuum electric field (1.5 mW average thermal power) at 250 kHz repetition rate and a high NIR-to-THz conversion efficiency of 2 × 10-3. This is achieved by photoexciting biased large-area photoconductive emitter with NIR fs pulses of μJ pulse energy. We demonstrate focussing of the THz beam by tailoring the pulse front of the exciting laser beam without any focussing element for the THz beam. A high dynamic range of 104 signal-to-noise is obtained with an amplifier based system.

Beam splitter plate (BS) divides optical pulse trains from the amplifier in pump and probe beam; Lenses (L1,L2) enlarge the pump spot and lense (L3) focus the beam; Emitter bias voltage U B is modulated at laser repetition rate; Electro-optic crystal (EO), quarter-wave plate (QWP), beam splitter cube (PBS) and two photodiodes (D1,D2) are used to probe THz transients. Note that there is a THz focus at the position of the EO crystal without use of additional optics, i.e. parabolic mirrors.

Fig. 2.
Fig. 2.

The time trace shows the maximum THz electric field detected in the EO crystal equals 17 kV/cm. The magnified part shows oscillations occurring due to absorption and reemission of THz radiation by water vapor. Because of the high SNR the magnified oscillations appear without visible noise. Next to the time trace window the corresponding (normalized) spectral amplitude is shown.

Fig. 3.
Fig. 3.

Maximum THz electric field as a function of excitation fluence and excitation spot size radius (1/e2) on the PC. The dashed lines in the inset correspond to the expected linear dependence in the vicinity of saturation effects. All measurement points were acquired at an acceleration field of 20 kV/cm to reduce additional saturation effects present at high bias electric fields [19].

Fig. 4.
Fig. 4.

Maximum THz electric field as a function of excitation fluence on the PC for different acceleration fields. The range where THz amplitude scales linearly with fluence is significantly extended at higher bias fields. The graph to the right shows a vertical cut of the curves in the left graph at a fixed excitation fluence of 12.4 μJ/cm2. A linear dependence of THz amplitude is observed up to acceleration fields of 40 kV/cm. At higher bias fields saturation of THz emission occurs due to ultra-fast transfer of free carriers into the side-valleys of GaAs [19].
