Graphene oxide saturable absorber on golden reflective film for Tm:YAP Q-switched mode-locking laser at 2m

Journal Article

A diode-pumped Tm:YAlO3 (Tm:YAP), solid-state Q-switched mode-locking (QML) laser was achieved for the first time by using a graphene oxide saturable absorber on gold reflective film. A pulse width for mode-locking inside the Q-switch envelope of 2ns with a repetition rate of 156.25MHz has been obtained at the central wavelength of 1973nm (32nm full width at half maximum). The measured maximum average output power amounts to 464 mW under an incident pump power of 9.52W. By using graphene oxide saturable absorber on golden reflective film instead of the tail end cavity mirror, we not only achieved a broadened spectral region 2m laser, but also deepened the modulation of the QML. © 2012 Taylor & Francis.
