Title: Pulsed laser

Abstract

This patent describes a pulsed laser. It comprises pumped laser gain cells, each gain cell emitting amplified light within a different respective frequency range in first and second opposite directions; a corresponding plurality of first mirrors, each mirror disposed to receive the light emitted from or passed through the corresponding gain cell in the first direction, and reflecting the light back through the gain cell; a common second mirror, positioned to receive the light emitted by or passed through all of the gain cells in the second direction, reflecting a fraction of the light back to the gain cells and transmitting a fraction thereof; a light-dispersing device optically coupling between the common second mirror and each cell the light within the respective frequency range; and a mode locker interposed in the path of the light reflected by the common mirror and preferentially transmitting the phases of the respective frequencies that periodically reinforce to produce a high-amplitude pulse, whereby the light transmitted by the common second mirror consists of pulses when the individual gain cells operate continuously.
