A light source providing multi-longitudinal resonant waves, particularly by utilizing an optical parametric oscillator (OPO) to produce a broadband emission spectrum. By configuring the system to pump the OPO far above the oscillation threshold, tunable light of macroscopic power with a short coherence length is provided. The coherence may be further shortened by additional longitudinal mode scrambling.
