Abstract

This paper describes the development of synchronously pumped tandem OPO/OPO (optical parametric oscillator) and OPO/DFM (difference frequency mixing) devices based on a single PPLN crystal. Tandem intra-cavity devices are of interest for efficient conversion from the near-infrared (1.064 μm) to the mid-infrared because back-conversion is reduced and the near-infrared signal beam is also converted to the mid-infrared. The single crystal OPO/DFM device is phase matched by temperature tuning and 4.3 W (3 W at 3.9 μm 1.3 W at 2.35 μm) has been generated in the mid-infrared with a pump power of 25 W at 1.064 μm. The OPO/OPO produced an output power of 850 mW at 3.9 μm and 50 mW at 4.48 μm with a pump power of 7W.
