The Er:YAG laser has been shown to be a effective and safe tool for middle ear surgery, due to its wavelength of 2.94 μm matching a peak in the absorption spectrum of tissue. The development of a compact laser provides similar optical properties with the additional advantage of being a smaller and more flexible system. The laser-tissue interaction of the laser with porcine otic capsule bone, including photoacoustic effects and ablation characteristics are presented here and compared to those of an Er:YAG laser, to show its suitable for middle ear surgery. Photoacoustic effects were recorded using a piezo-electric film. Ablation rates were determined by mass loss per pulse and etch depth per pulse.
