Backward optical parametric oscillation has attracted attention for cavityless spectral
narrowband generation based on perfect photon conversion. Few demonstrations have …

We report superior terahertz parametric generation from potassium titanyl phosphate (KTP)
over congruent-grown lithium niobate (CLN) and lithium tantalate (CLT) in terms of …

Abstract Quasi-phase-matching (QPM) technology is considered one of the efficient ways to
generate a coherent narrowband terahertz (THz) source. This review addresses two main …

Backward terahertz pulses were converted from ultrafast pulses of a laser amplifier within
multiperiod periodically poled LiNbO_3 (PPLN) wafers. The average output powers of more …

We studied terahertz (THz) optical and dielectric properties of stoichiometric lithium tantalate
(sLT) from room down to liquid nitrogen temperature in the range of 0.15–1.8 THz using …

Dielectric material parameters of lithium tantalate (LT) in the terahertz region have been
investigated using terahertz time-domain spectroscopy (THz-TDS). Undoped congruent …

We report on Y-branch superficial depressed-cladding waveguides fabricated by
femtosecond laser writing of MgO: LiTaO3 crystal. The cladding waveguides with a …

Continuous tuning of terahertz waves was demonstrated with seamless change in grating
period in a periodically poled stoichiometric lithium tantalite (SLT) crystal. The periodically …

Femtosecond optical pulse is used to generate narrow-band terahertz pulses depending on
a quasi-phase-matched condition in periodically poled lithium niobate (PPLN) and …

We first examined a temperature-dependent Sellmeier equation for the extraordinary
refractive index of MgO-doped stoichiometric LiTaO 3 (MgO: SLT) crystal via frequency …
