Experimental demonstration of bending resilience of focal spots created with and without mode selection. (a) Plot of normalized peak focal intensity of 150 near-boundary focal spots created using AMs (red) and the same focal spots created using HOMs (blue) with translation of the fiber distal tip. (b) Evolution of representative focal spots a1 and b1 created using AMs and HOMs respectively at the initial fiber position into a2 and b2 after a 2 mm translation of the distal tip. The displacement positions of the spots are marked in (a).
