Abstract
This paper continues the previous publication «Laser for generation of ultrashort pulses with controllable duration for robotics» [1] and concerns latest investigations of the novel technology of using a controllable Michelson interferometer as the laser resonator output mirror. The proposed algorithm of controlling phase modulation allowed to demonstrate the feasibility of preferential amplifying and extracting several subnanosecond radiation pulses with enhanced peak power from a train of synchronization mode pulses. The preferences, shortcomings and perspectives of the considered technology development are discussed.

Key words
Oscillator of ultrashort pulses, controllable Michelson interferometer, driver of phase electro optical modulator.
