Title:
FIBER LASER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/222022
Kind Code:
A1
Abstract:
Provided is a fiber laser circuit that enables an industrial laser to be generated. This fiber laser circuit includes a circuit A, wherein the circuit A includes, as the basic structure: a pulse stretcher unit 1 that stretches laser pulses from mode-lock laser pulses; a first fiber laser amplification unit 2 that amplifies the intensity of the laser pulses by ten times or more; a first frequency conversion unit 3 that converts the repetition frequency of the laser pulses; and a second fiber laser amplification unit 4 that amplifies the intensity of the laser pulses, of which the repetition frequency has been converted, by ten times or more.
