“…Assuming a desired output THz energy of 10 mJ, the necessary pump pulse energy is as high as 0.5 J, which implies using a pump spot area of ~100 cm 2 or spot diameter of ~11 cm. Currently, it is difficult to grow stoichiometric lithium niobate (sLN) to such size, motivating us to use congruent lithium niobate (cLN) since it can be produced in much larger sizes, though at a cost of slightly lower conversion efficiency [15]. If the lithium niobate crystal is cooled down to 10 K, pump to THz conversion efficiencies of up to 13% have been predicted [5].…”

The scope of applications that require intense and ultrafast THz fields has been increasing during the last years. Applications such as terahertz time-domain spectroscopy [1], the study of carrier dynamics in semiconductors [2], electric field gating of interlayer charge transport in superconductors [3], or THz assisted attosecond pulse generation [4] benefit from higher pulse energies than currently available, and so there is keen interest in scaling the peak power of the THz generation schemes. More recently, high peak power THz sources have been proposed for charged particle acceleration, undulation, deflection and spatiotemporal arbitrary manipulation too [5].There are different methods for generating high peak field THz pulses. Among them, difference frequency generation (DFG) and optical rectification (OR) are the most common. Sell et al. demonstrated that it is possible to use DFG between two parametrically amplified pulse trains to generate phase locked terahertz transients with peak electric fields of 10 8 MV/cm and center frequencies continuously tunable from 10 to 72 THz [6]. However, such methods typically exhibit fairly low photon conversion efficiencies due to the Manley-Rowe limit and are also restricted to high THz frequencies approaching the mid-IR spectral region due to limitations imposed by the phase matching condition in the DFG medium, such as GaSe or AgGaS 2 . Optical rectification, on the other hand, has been widely implemented to generate pulses at low THz frequencies [7]. Because the nonlinear process can be cascaded, over 100% of photon conversion efficiency has been demonstrated [8,9]. Of the common nonlinear materials used for OR, ZnTe presents the problem of free carrier absorption, limiting the total efficiency [10]. Lithium niobate presents multiple advantages such as large d eff , high damage threshold, low THz absorption, and large bandgap, but it requires tilted pulse front pumping techniques to achieve
