| Zusammenfassung: | A diode-pumped Yb:YAG laser with a novel edge-pumped composite Yb:YAG microchip laser has been demonstrated. At RT, continuous-wave generation with 50% slope efficiency in absorbed pump power is demonstrated from a 0.5 mm diameter hexagonal core of 2 at% Yb3+ ion doped YAG. Under quasi-continuous wave pumping with 2.4 Hz repetition rate and 2.5% duty cycle, laser emission with 42% slope efficiency and 41 W output peak power at 220 W input pump power was obtained from a microchip with 10 at% Yb doped YAG level in the core. The highest pulse energy of 1.5 J resulted under 17.5 J pumping pulse energy. 9 refs. |
