Abstract: We have designed an experimental setup to micro machine Fabry-Perot interferometer in silica and sapphire fiber with a Ti:sapphire femtosecond laser and in comparison with a nanosecond Nd:YAG laser at 355 nm. We achieved spot sizes of 5 µm with the Ti:sapphire and 20 µm with the Nd:YAG laser.
