| 英文摘要 | we demonstrate the incoherent beam combining (bc) of four high-power single-mode fiber lasers. adaptive fiber-optics collimators (afoc) of 0.5 kw-level are developed to correct the tip/tilt-type phase errors among beamlets. the maximum deflection angle of the afoc is about 0.29 mrad. a stochastic parallel gradient descent algorithm is employed as the tip/tilt control strategy. the tip/tilt control makes four separate laser beams overlap with each other in the far-field, and the average of normalized power-in-bucket increases from 0.171 in open loop to 0.798 in closed loop when 1.5-kw total output power is achieved. the precise tracking ability and control accuracy of this bc system are investigated. experimental results expose that thermal-blooming effect disturbs bc seriously when the total output power is up to kw-level, which could be mitigated by inducing air flow near the laser output. |
