Role of near-field enhancement in plasmonic laser nanoablation using gold nanorods on a silicon substrate: comment.

In this comment, we argue that the conlusion made by Harrisson and Ben-Yakar [Opt. Express 18, 22556 (2010)], which states that nanoablation with plasmonic nanorods depends on the enhancement of the Poynting vector rather than the one of the square of the electric field, is incorrect and not necessarily needed to explain their experimental results.
