The experimental study of passively Q-switched, LED-pumped Ce:Nd:YAG laser is reported. The active medium is a 3 mm diameter laser rod of 60 mm length, which is optically pumped with four segments of blue LEDs at 460 nm where each segment consists of 32 single LED. The 14 cm length optical resonator equipped with two dielectric mirrors and reflectivity, 99 and 93 percent at 1064 nm. Using a  passive optical switch with 96% initial transmission and 0.8 J electrical pumping energy, nearly 20 micro-joules, 240 ns pulse-width, and single Q-switch laser pulse was generated. 
Keywords: Passive Q-switch, LED pumping, Ce:Nd:YAG laser
