We report on a compact and highly efficient diode-end-pumped TEM>00 Nd:YVO4 slab laser with an output power of 103 W and beam quality M2≤≦1.5 . The optical-to-optical efficiency was 41.5%. In electro-optically Q -switched operation, 83 W of average power at a pulse-repetition rate of 50 kHz with a pulse length of 11.3 ns was obtained. At a pulse-repetition rate of 10 kHz, 5.6 mJ of pulse energy, and 870 kW of peak power were measured.
