摘要
A synchronously pumped optical parametric oscillator (OPO) comprises a nonlinear optical medium positioned in an optical resonator (e.g., a ring resonator) and is pumped by a pump laser source. A first arrangement includes a positioning mechanism for translating the nonlinear optical medium so OPO resonant modes propagate through one of multiple longitudinal regions arranged for differing odd orders of quasi-phase-matching. A second arrangement includes a pump fiber laser oscillator stretched to adjust its repetition rate to match that of the OPO. A third arrangement includes a time-domain-multiplexer (TDM) fiber loop between a pump fiber laser oscillator and fiber laser amplification stage(s). The TDM loop increases the pump repetition rate to enable increased average pump power without increased peak power.
