title: Generation of low repetition rate subnanosecond pulse in an optimal doubly QML Nd:Lu0.15Y0.85VO4 laser with EO and Cr⁴⁺:YAG.
abstract: Employing different output couplers and Cr4+:YAG saturable absorbers with different initial transmittances in a Q-switched mode-locked (QML) Nd:Lu0.15Y0.85VO4 laser, the symmetry of the Q-switched envelope was optimized and the envelope duration was shortened. By applying the above mentioned optimization into an EO/Cr4+:YAG dual-loss-modulated QML Nd:Lu0.15Y0.85VO4 laser, the Q-switched envelope can be further compressed until only containing one mode-locking pulse. Mode-locking pulse energy and peak power up to 1.15 mJ and 3.15 MW, respectively, were achieved. The rate equation theory was utilized to analyze the experimental results, and the theoretical simulation was basically in accordance with the experimental data.
