Abstract

We report on a compact, efficient, and reliable monolithic Nd:YVO4 slab oscillator–amplifier with an output power of 29.3W in cw operation and an optical-to-optical efficiency of 24%. In electro-optically Q-switched operation, 28.8W of average power at a repetition rate of 100kHz with a pulse width of 15ns was measured. The RMS stability of the pulse energy is better than 1.7%. The beam quality M2 in both cw and pulse models was under 1.3.
