Abstract
Higher-order Poincaré sphere (HOPS) beams with spatially variable polarization and phase distributions are opening up a host of unique applications in areas anging from optical communication to microscopy. However, the flexible generation of these beams with high peak power from compact laser systems remains a hallenge. Here we demonstrate the controlled generation of HOPS beams based on coherent beam combination (CBC) from an Yb-doped multicore fiber (MCF) amplifier. Using a spatial light modulator to adaptively adjust the wavefront and polarization of the signals seeded into the individual cores of the MCF various structured beams including cylindrical vector beams, and both 1st and 2nd order vortex beams) were generated with peak powers up to 14 kW for ~92 ps pulses.
