Passive Q-switching-at 1.54-micrometer of a Er-Yb:GdCa4O(BO 3)3 laser with a Co :MgAl2O4 saturable absorber

• A train of Q-switched pulses is formed in a diode-pumped microchip laser consisting of an Er-Yb:GdCa4O(BC3)3 active and Co2+:MgAl2C4:Co passive element. The pulses' durations were in the range of 1.6-6 ns and maximum output power was 88.2 mW at 928 mW of absorbed power.
