Abstract

We have developed a single-emitter laser-diode (LD)-pumped cavity-dumped ytterbium-doped yttrium aluminum garnet (Yb:YAG) laser. For an absorbed pump power of 1.98 W, the slope efficiency and the optical-to-optical conversion efficiency were 46.9% and 37.9%, respectively. The absorption efficiency was 82.0%. An average output power of 748 mW and a pulse energy of 15µJ were obtained with a pulse repetition rate of 50 kHz. The pulse width was 10 ns. To our knowledge, these efficiencies are the highest values for single-emitter LD-pumped nanosecond pulse lasers as well as for LD-pumped cavity-dumped lasers without direct pumping with a pulse width of less than or equal to 10 ns.
