Abstract

We report an electro-optic Bragg modulator using a periodically poled lithium niobate (PPLN) crystal. We measured a half-wave voltage of 160 V when transmitting a 1064 nm laser through a 14.2 mm long, 780 μ m thick, 20.13 μ m period PPLN crystal at the Bragg angle. We also demonstrated a Q-switched Nd : Y V O 4 laser using such a PPLN Bragg modulator as its Q-switch, producing 7.8 ns , 201 μ J pulses at a 10 kHz repetition rate when pumped by a 19.35 W diode laser at 808 nm .
