Abstract
Er:YAG laser emitting at 2.94 μm are very precise instruments in medical surgery due to the high water absorption (a ~ 12,000 cm-1) in this wavelength range. These laser make a specific deposition of energy possible and therefore are promising devices especially in cataract surgery. Nevertheless, to be competitive to the ultrasound method that is commonly used in cataract surgery repetition rates of more than 200 Hz at output energies of 5 to 10 mJ are necessary.
