The LOCSET phase locking technique was also successfully extended, for the first time, into an Object In the Loop (OIL) configuration by utilizing light scattered off of a remote object as the .. Cascaded multi-dithering technique using PZT modulators for . - Springer. Among those, the LOCSET technique has remarkable performance in terms of the maximum number of beam elements to be combined and low residual phase error, compared with the other two methods, using only one detector . However, the LOCSET technique also faces a challenge as the number of beam elements increases.. Analysis and modeling of phase noise in LOCSET and the AFRL high power .. of coherently combining the elements in such an array is LOCSET. A potential drawback to the effectiveness in LOCSET is the increased phase noise that is present in higher power amplifiers. The theory of LOCSET and the impact of this noise on LOCSET is researched. A mathematical model of model is developed to study this issue.. LOCSET beam combining block diagram. PM represents phase . - ResearchGate. LOCSET technique can be operated in the context of self-referenced or self-synchronous [282, 283]. Various research has been conducted on CBC laser systems based on the LOCSET technique ..

. 2. LOCSET In order to coherently combine multiple lasers accurate control of the optical phase is required. Some of the more prominent methods of active phase control include heterodyne [25-26], Stochastic Parallel Gradient Descent (SPGD) [27-28], and LOCSET [17,21,29-30,33] phase locking techniques.. Coherent combining of pulsed fiber amplifiers in the nonlinear chirp .. CLP-LOCSET phase-modulates the low level (< −95 dB) inter-pulse coherent CW leakage and is not applied during the pulse so there are no intra-pulse modulation effects produced by the piston phase locking control loop. A schematic for CLP-LOCSET is shown in Fig. 5. CLP-LOCSET proved to have the best continuous coherent combination efficiencies .. Phase Dynamics of LOCSET Control Methodology. Optical path differences and noise adversely affect beam quality. An existing closed loop phase control methodology, called the locking of optical coherence by single-detector electronic-frequency tagging (LOCSET), corrects phase errors in real time by electronically detecting path length differences and sending signals to lithium niobate phase ..
