An all-fibre PM MOPA pumped high-power OPO at 3.82 microns based on large aperture PPMgLN

Lin, D., Alam, S.-U., Shen, Y., Chen, T. and Richardson, D.J. (2012) An all-fibre PM MOPA pumped high-power OPO at 3.82 microns based on large aperture PPMgLN At SPIE Photonics West, United States. 21 - 26 Jan 2012. (doi:10.1117/12.906364).

Record type: Conference or Workshop Item (Paper)


We report a large aperture PPMgLN based OPO generating 21W of average output power at a slope efficiency of 45%, pumped by the output from a polarization maintaining Ytterbium doped fiber MOPA operating at 1060nm producing 58W of average output power and 20ns pulses at a repetition rate of 100kHz. A maximum of 5.5W of optical power was recorded at the idler wavelength of 3.82µm without thermal roll-off. We have experimentally verified that the pulse rise/fall time plays a significant role in the OPO conversion efficiency and that further enhancement in the OPO conversion efficiency will be possible using sub-nanosecond rise and fall times.
