Low-voltage Q switching of diode-pumped Er:Yb:glass laser by a BBO Pockels cell

摘要

Abstract: Seeded Q-switched pulsing in a diode-pumped Er-Yb glass laser has been experimentally demonstrated. The Q-switch is a beta-barium borate Pockels cell. The voltage applied to the BBO is much lower than the voltage needed to hold off the laser. This allows low-power, free-running lasing to seed the Q-switched laser-pulse. Q-switched operation is accomplished with a reduction by a facto of 5 to 8 below the full hold-off voltage. Measurements on this system also allows an estimation of the time of the energy transfer between Yb and Er ions. !6
