A high-average-power, laser-diode-pumped, picosecond-pulse regenerative amplifier was developed using the thin-rod Yb:YAG (yttrium aluminum garnet) laser architecture. This architecture has a complete set of favorable properties for the cost-effective, high-average-power, and high-peak-power lasers. These include low amplified spontaneous emission with high gain and high repetition rate. For the amplifier system, an average output power of 20 W was achieved at a pulse repetition rate of 100 kHz, which corresponds to an output pulse energy of 200 mu J with an output pulse width of 2 ps.
