We experimentally demonstrated optical parametric amplification with five pumps coming from two different oscillators. By spreading those partially mutually incoherent pumps at 532 nm over different phase-matching directions around a signal at 725 nm, we obtained a pumps-to-signal efficiency of 27%.
