Y-Fi™ OPA is KMLabs’ vertically integrated, collinear optical parametric amplifier pumped by a Y-Fi HP. The class leading pulse duration of the 1035 nm centered Y-Fi HP results in both a stable, coherent white light seed source and an exceptionally high conversion efficiency into the short-wave (1250-1800 nm) and mid-wave (2.4 – 4.4 μm) infrared.
