Mode-locked sub-picosecond operation of Yb- ,Er- and Tm:Hodoped fiber lasers operating at 1.05 mu m, 1.56 mu m and 1.99 mu m, respectively, is demonstrated using the same sample carbon nanotube-based saturable absorber mirror. A mesh of single-walled carbon nanotubes was deposited on an Ag-mirror using a one-step dry-transfer contact press method to combine broadband saturable absorption and high reflectance properties. The novel fabrication method of the polymer-free absorber and device parameters determined using nonlinear reflectivity measurement are described in detail. To our knowledge the observed operation bandwidth of similar to 1 mu m is the broadest reported to date for a single carbon nanotube-based saturable absorber. (C) 2009 Optical Society of America
