Abstract [en]

We report on the first single-frequency parametric source tunable in the longwave infrared with an output energy of 1 mJ. The source is then used in a lidar to detect chemicals in the vapor phase.

Abstract [en]

We demonstrate broadband parametric amplification in GaSe crystal in noncollinear geometry. Seed pulses spanning 1.5-2.6μm are produced by cascaded χ(2) nonlinearity in a periodically poled Rb:KTP crystal. Amplified pulse bandwidths supporting 10-15fs transformlimited pulse durations at ~2μm central wavelength are achieved.

Abstract [en]

We report on experimental implementation of a ferroelectric metasurface using an x-cut KTiOPO4 (KTP) crystal for efficient manipulation of terahertz (THz) radiation. Based on the multipolar resonances that are accommodated in KTP micro-blocks in a square array, the metasurface is fabricated by precision diamond-blade dicing. Adjusting the size of the KTP micro-blocks to tailor the relative spectral positions of the anisotropic multipolar resonances, we demonstrate a subwavelength-thin THz polarizer that functions as a transparent film in the y-direction and a magnetic mirror in the z-direction with a transmission contrast of 13 dB near 0.37 THz (820 mu m). The ferroelectric-based all-dielectric metasurface will provide a versatile platform to engineer the THz waves in the far field and could potentially be combined with THz generation in the same material.
