Significant defects and CNT agglomeration were avoided by optimizing the process steps, including stabilized CNT dispersion in dimethylformamide and the gelation of silica sol. After verifying undamaged nanomorphologies and optical properties of the enclosed CNTs via nonlinear absorption checks, we successfully demonstrated all-fiber, mode-locked laser modulating the intracavity absorption with the CNT-incorporated glass transferred onto a laser component. Resultant spectral width and repetition rate of the laser pulse output were 1.1 nm and 2.96 MHz, respectively. (C) 2010 Elsevier B.V. All rights reserved.
