| Abstract: | A room-temperature, diode-pumped, pulsed Yb:YAG ceramic free-running laser with a 78% slope efficiency has been demonstrated. It has been shown that fine tuning of the mode diameter to the diameter of the pumped volume with a ratio of the pump to the mode diameter of 0.6 is important for achieving maximum laser efficiency with a Gaussian-like beam profile. A regenerative Yb:YAG ceramic amplifier with a maximum output energy of 14.5 mJ and a super-Gaussian beam profile is demonstrated. |
