Double-wall carbon nanotube absorber for passively mode-locked Yb 3+ :Sc 2 SiO 5 laser

Journal Article

Double-walled carbon nanotube saturable absorber (DWCNT-SA) fabricated by vertical evaporation method was first used in passively mode-locked Yb 3+:Sc 2SiO 5 (Yb:SSO) laser to our knowledge. The laser operated at a repetition frequency of 89 MHz with the central wavelength of 1062.6 nm. A pulse duration of 15 ps was produced with an average power of 818 mW and a highest pulse energy of 9.2 nJ for a DWCNT-SA mode-locked laser. In addition, laser pulses as short as 1.6 ps were generated by inserting a pair of SF10 uncoated prisms into the cavity to compensate the cavity dispersion with a maximum peak power of 2.65 kW. © 2012 by Astro Ltd.
