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 12ns pulse width and 0.74kW laser pulses at 1064-nm wavelength from a diode-pumped Nd:YVO4 laser with continuous 1.2-W pump power at 809-nm wavelength.

CW performance of the Nd:YVO4 laser with (solid curve) and without (dashed curve) a 100-V voltage applied to the EO PPLN. With the 100-V voltage, the laser threshold was increased from 400 mW to 1.4 W because of the polarization-rotation effect from the EO PPLN crystal.
