An Innovative Electro-Optic Q-Switch Technology in 1064 nm and 1319 nm Dual-Wavelength Operation of a Nd:YAG Laser

An innovative electro-optic (EO) Q-switch technology in 1064 nm and 1319 nm dual-wavelength operation of a Nd:YAG laser is illustrated. Output energy of 4.6 mJ and pulse width of 400 ns for 1064 nm and output energy of 8.7 mJ and pulse width of 80 ns for 1319 nm are achieved simultaneously at the repetition rate of 1 Hz and pumping voltage of 750 V by using this bias voltage electro-optic Q-switched-technology when the voltage on LiNbO₃ crystal is 2254 V. The strong line of 1064 nm in Q-switched operation is inhibited efficiently.
