Abstract

We evaluation the operation of 1064 nm electro-optically Q-switched Nd: YAG rod laser that is end pumped by laser diode. The width of 400, 350 and 250 nsec were obtained at reflectivity of output coupler mirror of 99, 98 and 95%, respectively and also observed the optical resonator (L = 70-90 mm) and input optical power (350-430 mW) is effective in the value of energy per pulse (6-23 μJ) and pulse width (250-600 nsec). The optimum switching time of Q-switching is obtained at 750 μsec and the beam that a near-diffraction-limited quality.
