Abstract

Single-cycle terahertz (THz) transients in the frequency range 0.37THz with electric-field amplitudes of more than 400kVcm are generated by four-wave mixing of the fundamental and the second harmonic of 25fs pulses from a Ti:sapphire amplifier in ionized air. These transients are fully characterized by electro-optic sampling with ZnTe and GaP crystals. One can tune the center frequency of the THz transients by varying the length of the incident pulse. The electric-field amplitude increases linearly with the incident pulse energy.

Schematic of the setup used for THz generation. Incident upon the lens is the output of a Ti:sapphire multipass amplifier with pulse energies of as much as 500 μ J and pulse lengths as little as 25 fs . The BBO crystal, of 0.1 mm thickness, is cut for type I phase-matched second-harmonic generation. In the focal region the intensity is high enough to generate a plasma in nitrogen gas, which then acts as the source of THz radiation by a χ ( 3 ) process.

(a) Electric-field transients measured by electro-optic sampling in ZnTe for several lengths of the incoming pulse (pulse energy held constant at 0.5 mJ ), varied by changing the amount of chirp. (b) Electric-field transient for a 25 - fs pulse measured by electro-optic sampling in a 0.1 mm thick GaP crystal. (c) Spectra obtained by Fourier transform of the transients. For the shortest pulse length of 25 fs the spectrum measured with ZnTe as the electro-optic crystal shows a high-frequency cutoff near 4 THz .

Fig. 3

Amplitude of the electric-field transients measured by electro-optic sampling in ZnTe for several energies of the incoming pulse at 800 nm . The lines show the power-law dependencies. The best fit is obtained for exponent of x = 1 ; i.e., the field amplitude depends linearly on the input-pulse energy.
