Abstract: A high-power compact repetitively pulsed Nd:YAG laser with transverse diode pumping and multiloop self-pumped phase-conjugate cavity is proposed. Pulse trains with an energy of 1.5 J and beam quality parameter of $M^2\le$ 1.2 are generated at a divergence of 0.4 mrad and luminance of 5 $\times$ 10$^{14}$ W/(cm$^2$ sr). The peak power of single-frequency pulses is greater than 15 MW at an energy of 170 mJ and a laser bandwidth of 300 MHz.
