High-power single-spatial-mode near-IR laser diodes are mixed in periodically poled LiNbO{sub 3} (PPLN) to generate broadly tunable mid IR-radiation. Conversion efficiencies to the mid IR up to 0.017{percent}/W are demonstrated, and up to 31 {mu}W of power is generated at the spectroscopically important 4.3-{mu}m wavelength. We achieved broadband mid-IR tunability by mixing a wave- length-tunable laser-diode pump source with a fixed-wavelength master oscillator power amplifier laser-diode signal source in a PPLN sample that has a poling period that varies from 21.0 to 22.6 {mu}m in the direction transverse to the beam propagation. We generated mid-IR radiation from 4.1 to 4.3 {mu}m with these laser sources, using a fixed 22.0-{mu}m period region of the sample. {copyright} {ital 1996 Optical Society of America.}
