Title:
DUAL-WAVELENGTH LASER AND RELAY AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2023/226752
Kind Code:
A1
Abstract:
A dual-wavelength laser and a relay amplifier, belonging to the technical field of optical fiber communications. The dual-wavelength laser comprises a three-level laser module (1), a four-level laser module (2), and a first pumping source (3). The gain mediums of the three-level laser module (1) and the four-level laser module (2) are both optical fibers at least doped with ytterbium ions. The first pumping source (3) outputs to the three-level laser module (1) a pumped light of a first wavelength; the three-level laser module (1) absorbs the pumped light of the first wavelength, radiates light of a second wavelength, and outputs to the four-level laser module (2) the unused first pumped light among pumped light of the first wavelength. The four-level laser module (2) absorbs the first pumped light and radiates light of a third wavelength. Thus, laser having two different wavelengths can be output by using one dual-wavelength laser.
