High Energy THz Pulse Generation by Tilted Pulse Front Excitation and Its Nonlinear Optical Applications
József András Fülöp, László Pálfalvi, Gábor Almási, János Hebling
Generation of high energy THz pulses by tilted pulse front excitation is reviewed. The basic idea and the realized setups are described. Properties of THz pulses generated by using different pump lasers are summarized. Nonlinear optical effects induced by the high energy THz pulses were observed, such as nonlinear refraction, self-phase modulation, saturation of THz absorption, and free carrier generation. The main results on these phenomena are described. The possibility of using THz pulses as a quasi-dc field for increasing the cut-off frequency in high harmonic generation is analyzed. The THz generation setup used in recent experiments is analyzed and arrangements for achieving better THz beam quality and higher THz pulse energy are considered. Finally, some results of calculations indicating significantly increased generation efficiency of 0.2-THz pulses compared to generation efficiency of 1-THz pulses are presented.

Tilting the pump pulse front has been proposed for efficient phase-matched THz generation
by optical rectification of femtosecond laser pulses in LiNbO3 (Hebling et al., 2002). By using
amplified Ti:sapphire laser systems for pumping, this technique has recently resulted in
generation of near-single-cycle THz pulses with energies on the 10-μJ scale (Yeh et al., 2007,
Stepanov et al., 2008). Such high-energy THz pulses have opened up the field of subpicosecond
THz nonlinear optics and spectroscopy (Gaal et al., 2006, Hebling et al., 2008a).
The method of tilted-pulse-front pumping (TPFP) was introduced as a synchronization
technique between the optical pump pulse and the generated THz radiation.
Synchronization was accomplished by matching the group velocity of the optical pump
pulse to the phase velocity of the THz wave in a noncollinear propagation geometry.
Originally, TPFP was introduced for synchronization of amplified and excitation pulses in
so called traveling-wave laser amplifiers (Bor et al., 1983). By using such traveling-wave
excitation (TWE) of laser materials, especially dye solutions, extremely high gain (109) and
reduced amplified spontaneous emission could be obtained (Hebling et al., 1991).
Contrary to the case of TWE, when TPFP is used for THz generation by optical rectification,
a wave-vector (momentum) conservation condition or, equivalently, a phase-matching
condition has to be fulfilled. It was shown (Hebling et al., 2002), that such condition is
automatically fulfilled if the synchronization (velocity matching) is accomplished. The
reason is that in any tilted pulse front there is present an angular dispersion of the spectral
components of the ultrashort light pulse and there is a unique connection between the tilt
angle of the pulse front and the angular dispersion (Bor & Rácz, 1985, Martínez 1986,
Hebling 1996).
Angular dispersion was introduced into the excitation beam of so called achromatic
frequency doubler (Szabó & Bor, 1990, Martínez, 1989) and sum-frequency mixing
(Hofmann et al., 1992) setups in order to achieve broadband frequency conversion and
keeping the ultrashort pulse duration. It was pointed out that in non-collinear phasematched
optical parametric generators (OPG) and optical parametric amplifiers (OPA) tilted
pulse fronts are expected (Di Trapani et al., 1995). TPFP was used in the non-collinear OPA (NOPA) producing sub-5-fs pulses (Kobayashi & Shirakawa, 2000). The different aspect of tilted pulse front and angular dispersion is usually not mentioned in these papers dealing with broadband frequency conversion.
It is well known that the bandwidth of parametric processes is connected to the relative group velocities of the interacting pulses (Harris, 1969). Phase matching to first order in frequency can also be formulated as matching the group velocities of (some of) the interacting pulses. In schemes utilizing angular dispersion for broadband frequency conversion it is important to consider the effect of angular dispersion on the group velocity for a precious connectionbetween the Fourier-domain and the spatio-temporal descriptions. In this Chapter, we give a comprehensive overview of the different types of applications relying on TPFP or angular dispersion with an emphasis on THz generation. The connection between pulse front tilt, group velocity and angular dispersion will be discussed for each type of application.

Single-cycle terahertz pulses with amplitudes exceeding 1 MV/cm generated by optical rectification in LiNbO3
Using the tilted-pulse-intensity-front scheme, we generate single-cycle terahertz (THz) 
pulses by optical rectification of femtosecond laser pulses in LiNbO3. In the THz 
generation setup, the condition that the image of the grating coincides with the 
tilted-optical-pulse front is fulfilled to obtain optimal THz beam characteristics and 
pump-to-THz conversion efficiency. The designed focusing geometry enables tight 
focus of the collimated THz beam with a spot size close to the diffraction limit, and the 
maximum THz electric field of 1.2 MV/cm is obtained.

TeraHertz Spectroscopy
The most efficient way to produce TeraHertz pump pulses in a tabletop setup is the “tilted wavefront generation” [1].
Starting from a Ti:Sa amplified laser system at 1 kHz of repetition rate (about 1 W of power), we obtained THz pulses with more than 100 nJ of energy corresponding to a fluence higher than 10 μJ/cm2 (Fig. 1). With this setup we are studying the optical properties of GaAs just below the band gap as we expect a huge variation due to the Dynamical Franz-Keldysh effect (DFKE) [2]. The probe light at 900 nm was filtered from the super-continuum spectrum (Fig. 2).
This setup shows good resolution (ΔR/R ≳ 10-4) and will be soon upgraded with an array detection apparatus in order to perform one-shot broadband white-light probe experiments.

Terahertz Technology Enters The Mainstream, Enabling Better Performance In A Wide Range Of Applications

A solid state technology platform developed by scientists in Italy and France is said to open the door to the use of THz photonics in a range of applications.

Although there has been much research in THz technology, the team of researches says one missing piece has been a complementary detection technology. To solve this issue, the scientists used an approach that exploits the excitation of plasma waves in the channel of field effect transistors (FET). Alongside creating the first FET detectors based on semiconductor nanowires, the team also developed the first THz detectors made of mono- or bilayer graphene.

"Our work shows that nanowire FET technology is versatile enough to enable 'design' via lithography of the detector's parameters and its main functionalities, " said leader of the Terahertz Photonics Group.

According to the team, the nanowire detector operates at room temperature and can detect frequencies in excess of 3THz, with maximum modulation speed in the MHz range.

The team now plans to 'push the device's performance in the ultrafast detection realm', as well as integrating nanowire detectors with THz quantum cascade microlasers. "This will allow us to take THz photonics to a whole new level of 'compactness' and versatility, where it can finally begin to address many 'killer' applications."

Another team has stepped further in terms of ultrafast detectors operating at room temperature in sub-THz region (40 GHz - 0.7 THz). Ultrafast detectorsproduced by TeraSense consistently demonstrate response time of less than 150 ps. This was confirmed by direct observation of its impulse response function. The detector was excited by 200 nJ 1 ps laser pulse with a broad spectrum ranging from 0.1 to 3 THz, and its response was recorded by a high speed oscilloscope. The response function shows rise and fall times of 150 ps limited by the oscilloscope 4 GHz bandwidth.

The measured short response time makes it possible to use our detectors for straightforward investigation of fast transient processes in THz-science and telecommunication. TeraSense detectors are sensitive in a wide frequency range. However, their frequency response is not continuous, but consists if multiple bands (peak structures). Positions of the peaks in responsivity curve can be tuned at manufacturing stage to suit specific client’s requirements.

Our ultrafast high-sensitive sub-THz detectors are meant for exploring fast-changing and transient sub-THz signals and impulses. Terasense detectors are actually expediting the advent of ultra-high-speed wireless telecommunication networks that is about to happen in the nearest future. Terasense ultrafast detectors are also an ultimate tool for characterization, calibration and tuning of impulse sub-THz sources.
