Abstract

We proposed a novel THz generation technique beyond the limitation of the input optical pulse width, based on phase modulation via cascaded χ (2) process. When intense THz electric field generated by optical rectification lies in electro-optic (EO) crystal, emitted THz field gives phase modulation to the optical excitation pulse. The phase modulation causes excitation pulse narrowing and consequently gives rise to the enhancement of conversion efficiency and THz wave bandwidth broadening. We experimentally realize this generation technique with high χ (2) EO crystal LiNbO3 and with subpicosecond pulse from Yb-doped fiber laser. It opens new concept of THz technologies.

Schematic diagram of THz generation technique beyond limitation of the input optical pulse width. Simultaneous optical rectification (OR) and optical pulse phase modulation (PM) processes bring to the narrowing of both optical and THz pulses.

(a) Temporal profile of emitted THz radiation at different excitation powers 0.95, 3.7, and 8.5 µJ. We evaluate net profile (colored curves) with the assumption of 0.60 ps sampling pulse duration from EO signal (gray curves). (b) Input power dependence of interval between maximum and minimum electric field times. c Input power dependence of the maximum electric field calibrated form EO signal. Inset shows the scheme of experimental setup.

Fig. 4.

The position dependence of THz radiation on the surface of LiNbO3. Upper shows the output power densities of THz radiation, which is normalized by the square of input power. Lower shows corresponding time intervals between maximum and minimum electric field locations. We set the original where power density is the maximum at 0.8 µJ. We measured THz electric fields as shown in Figs. 1 and 2(a) at the position of d=0.6 mm.
