We demonstrate a sub-nanosecond Joule-class room-temperature diode-pumped solid-state chip laser comprising of periodically bonded Nd:YAG and sapphire crystal plates and operating at 25 Hz, delivering the peak power over 3 GW. In addition, a model describing parasitic oscillations in a composite, high-gain media is developed.
