| 摘 要： | The passively Q-switched and mode-locked （QML） characteristics in a diode-pumped Nd： GdVO4 laser with Cr^4＋： YAG saturable absorbers have been demonstrated. A maximum average output power of 710 mW has been obtained in the QML laser. The maximum energy of a single Q-switched pulse is 52.5μJ, with the corresponding pulse width of 30 ns and the peak power of 1.75 kW, at the incident pump power of 7. 75 W. The repetition rates of the Q-switched envelope and the mode-locked laser pulse are 16.7 kHz and 680 MHz, respectively.

| Abstract: | The passively Q-switched and mode-locked ( QML) characteristics in a diode-pumped Nd∶GdVO4laser with Cr4+∶YAG saturable absorbers have been demonstrated. A maximum average output power of 710 mW has been obtained in the QML laser. The maximum energy of a single Q-switched pulse is 52.5μJ, with the corresponding pulse width of 30 ns and the peak power of 1.75 kW, at the incident pump power of 7.75 W. The repetition rates of the Q-switched envelope and the mode-locked laser pulse are 16·7 kHz and 680 MHz, respectively. |
