✦ Synopsis

The diode-pumped passively Q-switched and Qswitching mode-locked Yb:Y2Ca3B4O12 lasers with V:YAG as saturable absorber are demonstrated in this paper. In the Qswitched regime, an average output power of 150 mW is obtained under the absorbed pump power of 6.6 W; the pulse width is 46 ns with the pulse repetition rate of 11 kHz, corresponding to the single pulse energy and peak power of 14 μJ and 296 W, respectively. For the Q-switched mode locking, the average output power of 223 mW is obtained with a repetition rate of 112 MHz. Moreover, due to the reabsorption effect, the emission wavelengths vary evidently with the different operation situation.
