We demonstrate a compact and efficient diode-end-pumped TEMinfinity laser w
ith output power of 30 W for 48 W of incident pump power by use of two coat
ed Nd:YVO4 crystals to form a thermally stabilized flat-flat cavity. In Q-s
witched operation 25 W of average power at a pulse-repetition rate of 100 k
Hz and similar to 0.9-mJ pulse energy at a pulse-repetition rate of 10 kHz
were produced. (C) 2000 Optical Society of America OCIS codes: 140.3480, 14
