摘要： A method for generating THz radiation comprises illuminating a semiconductor crystal with an optical pulse train. The semiconductor crystal comprises alternating parallel crystal domains, with each domain having a crystal orientation inverted with respect to adjacent domains. The optical pulse train propagates substantially perpendicularly relative to domain boundaries in the semiconductor crystal. The THz radiation is generated from the optical pulse train by optical down-conversion mediated by the semiconductor crystal. Optical path lengths through the crystal domains at least in part determine a frequency of the generated THz radiation. THz generation efficiency may be enhanced by placing the semiconductor crystal within an external resonant cavity, by placing the semiconductor crystal within a laser cavity, or by placing the semiconductor crystal within an OPO cavity. The semiconductor crystal may comprise zinc-blende, III-V, or II-VI semiconductor.

摘要： A source of terahertz radiation at a fundamental terahertz frequency is tunable over a fundamental terahertz frequency range, and is coupled into a first waveguide. The first waveguide supports only a single transverse spatial mode within the fundamental terahertz frequency range. A solid-state frequency multiplier receives from the first waveguide the terahertz radiation and produces terahertz radiation at a harmonic terahertz frequency. A second waveguide receives the harmonic terahertz radiation. The tunable terahertz source can comprise a backward wave oscillator with output tunable over about 0.10-0.18 THz, 0.18-0.26 THz, or 0.2-0.37 THz. The frequency multiplier can comprises at least one varistor or Schottky diode, and can comprise a doubler, tripler, pair of doublers, doubler and tripler, or pair of triplers. The terahertz source can be incorporated into a terahertz spectrometer or a terahertz imaging system.

摘要： A method comprises spatially selectively irradiating in a predetermined pattern with an output beam of a laser system an interface between a polymer substrate and a metal film on the polymer substrate. The polymer substrate is substantially transparent to the output beam of the laser system; the metal film absorbs a substantial fraction of the output beam. Laser system output comprises a sequence of pulses. Beam size at the polymer/metal interface, pulse energy, and pulse duration are selected so that each pulse from the laser system that irradiates an area of the polymer/metal interface substantially completely removes by ablation the metal film from at least a portion of the irradiated area without substantially altering the surfaces or bulk of the polymer substrate and without leaving on the polymer substrate or on remaining areas of the metal film substantial residue of metal that resolidified after being melted by the laser irradiation.
