Experimental explorations of the high-order Gaussian mode transformation based on blind-optimization adaptive optics
چکیده انگلیسی
We present research on high-order Gaussian laser beam transformation by using adaptive optics (AO) technique. Numerical simulation for a mode transformation system based on stochastic parallel gradient descent (SPGD) algorithm was accomplished, along with experimental results obtained for a transformation of TEM20 mode with 37 control channels. The far-field energy centrality of TEM20 mode was advanced and the evaluation function increased more than a factor of 6 after transformation. The experiments results indicate the feasibility of blind-optimization AO in mode transformation system.
