Multiband generation of mid infrared by use of periodically poled lithium niobate.
We report the generation of simultaneous multiband mid-infrared laser output by use of periodically polled lithium niobate pumped by the 1.54-microm output from a KTP optical parametric oscillator. The multiband source is capable of producing three mid-infrared wavelengths ranging from 2.5 to 4microm . In initial experiments we obtained output powers of 542 mW near 2.5microm and 453 mW near 4microm , with power conversion efficiencies of 30% and 25%, respectively. To the best of our knowledge, this is the first demonstration of this kind in the literature.
