A sealed leucosapphire cell containing rubidium vapor was used as an effective Q switching element for a flash lamp pumped Nd:YAG laser. The control of the laser parameters such as output energy, pulse length, and repetition rate by simple vapor temperature exchange has been demonstrated. Single giant pulses with energy 100 mJ and duration 20 ns were observed. Trains of 40 ns pulses separated by 6 microsecond(s) intervals were generated at the lowered temperature of the cell. The experiment was verified using a LiF Q switch. The cell is proposed for Q switching of high power and wide spectral range lasers.
