Abstract—In this paper the construction of a mechanically Q-switched diode side pumped Nd:YAG laser sys-
tem is described. It consists of a 50 cm long plane-plane resonator Q-switched with a combination of a rotating
prism and a mirror. With an optical to optical efficiency of 25% Q-switched pulses (@1064) of 48 mJ and 8 ns
are obtained at a rep-rate of 30 Hz with an output in near TEMoo mode. At a peak power of 6 MW the M2 value
is found to be 1.92. The laser is frequency doubled and then tested on a 50 
m thick tantalum foil which results
in circular holes of diameter 13 m in it.
