“…The magnitudes of d 24 and d 32 of BNA were alternatively characterized based on the phase-matched Type-2 SHG method. These values were reported as 5.5 ± 0.2 39 and 15.6 ± 0.9 pm/V 25 , respectively, both of which differ significantly from our results. Although the cause of these discrepancies must be clarified scientifically, we hypothesize that the Maker fringe method may produce more reliable results because the phase-matched SHG power drastically changes with even slight changes in temperature, tuning angle and so on.…”

“…Another possible explanation is our improved BNA crystal quality, which likely produces higher optical nonlinearity. As for the fitted refractive indices in our Maker fringe results, small disagreements are found with the refractive indices deduced from given Sellmeier equations 25,39 . However, because multiple refractive indices, thickness of sample and magnitude of second-order NLO coefficient simultaneously influence the shape of Maker fringes, such slight discrepancy as a result of least-square fitting can be inevitable.…”

Full elements of second-order nonlinear optical (NLO) tensor can be completely characterized for an organic NLO crystal for the first time. As-grown bulk N-benzyl-2-methyl-4-nitroaniline (BNA) crystal was processed to expose (100) and (010) crystal orientations with fine optical surfaces by using precision lathe and diamond blade. Then, every five nonvanishing second-order NLO coefficient of BNA can be determined quantitatively using the precisely processed crystals based on 1st-kind Maker fringe measurements. Our method makes it possible to clarify uncertain NLO property of any organic materials and to accelerate application study via precise device fabrications even for fragile organic materials.

“…Considering the two-level dispersion model for both the NLO and the electro-optic coefficient, we can estimate the highest electro-optic coefficient of BNA is r 333 = 24 pm/V at 1538 nm [100]. Although some experimental results suggest different values of the corresponding NLO and electro-optic coefficients [58,59,100], BNA crystal has been very successfully used for THz-wave generation applications, in particular in the pump wavelength regime at around 800 nm that is less optimal for high-nonlinearity red materials [101][102][103][104][105][106][107][108].…”

Organic crystals with second-order optical nonlinearity feature very high and ultra-fast optical nonlinearities and are therefore attractive for various photonics applications. During the last decade, they have been found particularly attractive for terahertz (THz) photonics. This is mainly due to the very intense and ultra-broadband THz-wave generation possible with these crystals. We review recent progress and challenges in the development of organic crystalline materials for THz-wave generation and detection applications. We discuss their structure, intrinsic properties, and advantages compared to inorganic alternatives. The characteristic properties of the most widely employed organic crystals at present, such as DAST, DSTMS, OH1, HMQ-TMS, and BNA are analyzed and compared. We summarize the most important principles for THz-wave generation and detection, as well as organic THz-system configurations based on either difference-frequency generation or optical rectification. In addition, we give state-of-the-art examples of very intense and ultra-broadband THz systems that rely on organic crystals. Finally, we present some recent breakthrough demonstrations in nonlinear THz photonics enabled by very intense organic crystalline THz sources, as well as examples of THz spectroscopy and THz imaging using organic crystals as THz sources for various scientific and technological applications.

“…For the configuration with an Nd:YAG laser (1.064 µm), a pulse duration of 5 ns and a repetition rate of 10 Hz, focused using a 150 mm focal lens (30 µm radius beam waist) at the BNA slab input surface, the surface damage was observed at the peak power of 0.96 GW/cm 2 [221]. For 800 nm Ti:Sapphire laser pulses (repetition rate of 100 Hz, pulse duration of 50 fs), the damage threshold of BNA is around 6 mJ/cm 2 [39].…”

In this review, we present a survey on the use of molecular nonlinear crystals in the context of terahertz (THz) photonics. The fundamentals of nonlinear optics for converting optical and infrared radiation into THz radiation with the basic theory of femtosecond optical rectification and difference frequency generation are described. Various types of phase-matching conditions that can be achieved in molecular crystals are discussed. It is shown that one of the unique features of molecular crystals is the ability to generate tunable narrowband terahertz radiation using femtosecond lasers. We also provide a detailed description of the most commonly used and promising molecular crystals such as DAST, DSTMS, OH1, HMQ-TMS, DCMBI, and GUHP. This review also presents a description of recent publications which show the prospects of using molecular nonlinear optical crystals in THz photonics.
