Abstract

To improve the efficiency of laser phacoemulsification we developed a compact, high-repetition-rate, high-average-power, diode-pumped, 2.94 μm TIR-cavity Er:YAG laser system. Laser parameters of 19.4% slope efficiency, 5 W of average output power at up to 300 Hz repetition rate and more than 1.5 W at 1 kHz are demonstrated. The special design results in low thermal lenses of 1.9 Dpt/W. This is a good condition for high laser system scalability.
