ABSTRACT
Following the generation of tunable terahertz waves from GaP in the 0.5- to 3-THz region, we extended the frequency region up to 7 THz, using an optical parametric oscillator and a YAG laser (1.064 μm). The tuning angle θ[SUBin] increased superlinearly in the 3- to 7-THz region, so that the total) reflection took place at 5 THz, which was avoided by rotating the crystal relative to the incident optic axis. As a result, terahertz output peak powers of 100 mW at up to 5.6 THz and 3 mW at 7 THz were obtained, at pump and signal energies of 3 mJ, respectively.

    In this work, we report the discovery of a vortex pinning source: semicrystalline defect wells in self-aligned nanostructured MgB[SUB2]. It is demonstrated that these aperiodic regions trap numerous crystal defects migrating along nanodomain boundaries during self-alignment and act as intense...

    We have found that an addition of SnO in a bismuth-borate glass, CaO–B2O3–Bi2O3–Al2O3–TiO2, decreases the optical absorption coefficient in the visible region, in which selective crystallization of TiO2 was observed after heat treatment. Since selective...
