This article [Opt. Eng. 49, 063801 (2010)] was originally published on 25 June 2010 with an error in the caption of Fig. 8.

The original figure caption read: “Optical power limiting performance of different weights of MWNTs in the solution of 5-mg PPE and 10-ml chloroform. ●, 0 mg; △ 0.075 mg; ▽, 0.125 mg; □, 0.25 mg; ♦, 0.375 mg; ○, 0.5 mg.”

The corrected caption should read: “Optical power limiting performance of different weights of MWNTs in the solution of 5-mg PPE and 10-ml chloroform. ●, 0 mg; ♦, 0.075 mg; □, 0.125 mg; ▽, 0.25 mg; △, 0.375 mg; ○, 0.5 mg.”

The corrected manuscript was published online on 19 October 2010.
