Abstract

High-power single-spatial-mode near-IR laser diodes are mixed in periodically poled LiNbO3 (PPLN) to generate broadly tunable mid IR-radiation. Conversion efficiencies to the mid IR up to 0.017%/W are demonstrated, and up to 31 μW of power is generated at the spectroscopically important 4.3-μm wavelength. We achieved broadband mid-IR tunability by mixing a wavelength-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 μm in the direction transverse to the beam propagation. We generated mid-IR radiation from 4.1 to 4.3 μm with these laser sources, using a fixed 22.0-μm period region of the sample.

Domain inversion pattern on the PPLN device. The pump and the signal beams are polarized in the crystallographic z direction and copropagate in the crystal-lographic x direction. Translating the crystal in the crystallographic y direction permits quasi-phase matching by use of the different poling periods.
