Abstract
We demonstrate a low-voltage and fast laser Q -switching by using an electro-optic periodically poled lithium niobate (EO PPLN) crystal. The half-wave voltage measured from the EO PPLN crystal was 0.36 V×d(μm)/L(cm), where d is the electrode separation and L is the electrode length. When a 13-mm-long EO PPLN was used as a laser Q switch at 7-kHz switching rate, we measured an ~12-ns pulse width and ~0.74-kW laser pulses at 1064-nm wavelength from a diode-pumped Nd:YVO 4 laser with continuous 1.2-W pump power at 809-nm wavelength.
