Abstract
Tangential phase-matching has been utilised to increase the conversion efficiency of the difference frequency mixing process for the generat ion of tunable infrared radiation in the lithium iodate crystal for th e first time. Using the Nd:YAG second harmonic and the same pumped dye laser radiations as input fundamental radiation sources, wide tunabil ity has been obtained for 2.6-7.7 mu m including the 6-6.7 mu m transm ission blockage region of the crystal due to two-photon absorption.
