Abstract

We demonstrate record conversion efficiencies of near 1% for nonlinear optical generation of narrowband (<1% bandwidth) THz pulses. These results are achieved using a novel laser source, customized for high efficiencies, with two narrow spectral lines of variable separation and pulse duration (≥250 ps). THz generation in 5% MgO doped PPLN crystals of varying poling period was explored for cryo- and room temperatures as well as different lengths. This work addresses an increasing demand for high-field THz pulses which has, up to now, been largely limited by low optical-to-THz conversion efficiencies.
