In some applications of a Michelson interferometer, in particular, when it is used in a laser resonator, the phase difference of radiation beams passing the interferometer optical branches must be stabilized with high accuracy. The proposed paper is devoted to experimental studying the long-term stability of several interferometer designs and choosing the optimal version for applying as a compound resonator mirror with the controllable reflection for generation of ultrashort laser pulses.

Abstract This paper presents the use of pulsed laser stimulation with picosecond and femtosecond laser pulses. We first discuss the resolution improvement that can be expected when using ultrashort laser pulses. Two case studies are then presented to illustrate the possibilities of the pulsed laser photoelectric stimulation in picosecond single-photon and femtosecond two-photon modes.

Percussion Drilling

AbstractA simplified analytical model is presented that predicts the depth progress during and the final hole depth obtained by laser percussion drilling in metals with ultrashort laser pulses. The model is based on the assumption that drilled microholes exhibit a conical shape and that the absorbed fluence linearly increases with the depth of the hole. The depth progress is calculated recursively based on the depth changes induced by the successive pulses. The experimental validation confirms the model and its assumptions for percussion drilling in stainless steel with picosecond pulses and different pulse energies.
