Highly efficient second harmonic and sum frequency generation of nanosecond pulses in a cascaded erbium doped fibre: PPLN source
By combining erbium doped fibre sources based on a large mode-area design and periodically poled lithium niobate we have obtained single pass conversion efficiencies of up to 83% (energy efficiency) for second harmonic generation into the near-IR (768nm) and 34% for sum frequency generation into the...
