Passive Coherent Polarization Beam Combination of a Four-Fiber Amplifier Array
IEEE Photonics Journal, 2013 We present what we believe to be a new architecture for coherent beam combination of a fiber amplifier array. Four polarization-maintained fiber amplifiers are passively coherent polarization beam combined by using an optical feedback in a ring cavity ...

Self-Synchronous Coherent Beam Combination [PDF]
2006 Digest of the LEOS Summer Topical Meetings, 2006 A completely novel concept for coherent beam combination is presented. The technique completely eliminates the need for a reference beam resulting in a dramatic simplification of electronic coherent beam combination without any compromise in performance.

Multiplexed emitting system for an energy-recovery-linac-based coherent light source
Journal of Synchrotron Radiation, 2023 Recently, a novel approach has been proposed to produce ultrashort, fully coherent high-repetition-rate EUV and X-ray radiation by combining an energy recovery linac (ERL) with the angular-dispersion-induced microbunching methodology.

HIBISCUS: Simulator for the development of control strategies for coherent beam combining lasers with PISTIL technique [PDF]
EPJ Web of Conferences, 2023 CBC (Coherent Beam Combining) is a key technology for the realisation of intense lasers. In this context, PISTIL (PISton and TILt interferometry), a precise metrology tool for measuring segmented wave surfaces, has been developed and used in particular ...

Study of high power CBC fiber laser systems with non-equal splitting ratio beam-splitters
Results in Optics, 2023 High power coherent beam combination (CBC) with non-equal splitting ratio beam splitters (BS) is studied. A BS-based two-channel CBC laser system has been built, and experiments with 50:50 BS and 30:70 BS has been carried.
