Abstract

We describe the first nanosecond PPLN OPO driven by a fibre laser. The source was frequency doubled by a PPLN sample, before pumping a second 20mm long PPLN crystal. The OPO threshold was <10µJ, with pump depletions of up to 45% and a tunable signal range of 945-1450nm, (1690-4450nm idler range). We demonstrated 130nm signal tuning by varying the pump wavelength and doubling crystal's temperature. Also, we achieved 15nm tuning with all crystals at a constant temperature. The results demonstrate the potential of the fibre laser: PPLN combination for practical, versatile and tunable sources.
