Description

We present an electro-optically Q-switched 2.79 μm Cr,Er:Y2.93Sc1.43Ga3.64O12 laser using LiNbO3 Pockels cell and undoped Y3Al15O12 plate polarizer. The optimal delay for triggering the Q-switch with respect to the peak of waveform of the flashlamp is found to be about 120 μs. The minimum pump threshold of 13.2 J is realized using the output coupler of reflectivity 74%. The maximum outputs of 72.3 mJ at 3 Hz and 35.4 mJ at 10 Hz repetition rates are obtained. The minimum pulse width is measured to be 31.9 ns. The far-field divergence angle of the laser beam is about 8.8 mrad. The influence of repetition rates on the output energy is also discussed
