Abstract

We report a technique for line-narrowing terahertz radiation produced through parametric generation. By incorporating an etalon within the idler-wave cavity of the parametric oscillator, radiation is generated with a linewidth of 1 GHz (freerunning linewidth 50-100 GHz) and with a center frequency continuously tunable over a band >50 GHz, settable anywhere within the coarse tuning range of the device (1-3 THz). When implemented within an intracavity cavity geometry, pulses of terahertz radiation of duration similar to 10 ns and energy similar to 30 nJ are generated at repetition rates up to 400 Hz (implying mean powers of >10 mu W and peak powers of similar to 3 W) in a compact device.
