ABSTRACT
A continuous-wave, tandem optical parametric oscillator (TOPO) based on a MgO-doped periodically poled LiNbO3 (MgOPPLN) is demonstrated. Because the MgOPPLN is tandemly pumped by the OPO's signal beam, it outputs simultaneously two groups of signal and idler with a single pump source. The entire range spans from 1398 to 1490â
nm, 1914 to 2107â
nm, 3720 to 4444â
nm, and 4849 to 5190â
nm, which is limited by periods of the MgOPPLN and cavity mirror coatings. The TOPO, whose oscillation threshold of pump power exceeds 7â
W, can be easily triggered by marginally increasing the pump power as long as the OPO process occurs. The maximum idler powers are respectively 2.6â
W (at 3896â
nm) and 34â
mW (at 4863â
nm), and the corresponding signal powers are both nearly 100â
mW.
