We present a relatively simple method for efficiently transforming a single high-order mode into a nearly Gaussian beam of much higher quality. The method is based on dividing the mode into equal parts that are then combined coherently. We illustrate the method by transforming a Hermite-Gaussian (1, 0) mode with Mx2 = 3 into a nearly Gaussian beam with Mx2 = 1.045. Experimental results are presented and compared with theoretical results.
