| 英文摘要 | A single wavelength laser module utilizes difference-frequency light and includes a first laser device for oscillating light having a first wavelength and a second laser device arranged parallel to the first laser device for oscillating light having a second wavelength, an optical waveguide device arranged next to the output ends of the first and the second laser device, and an output optical fiber arranged next to the output end of the optical waveguide device. The optical waveguide device includes a coupling waveguide region and an optical wavelength conversion region. The coupling waveguide region combines light having the first wavelength and the second wavelength into a single waveguide by being optically coupled directly to the first and the second laser device. The optical wavelength conversion region includes an optical waveguide for generating difference-frequency light between the first wavelength and the second wavelength. The coupling waveguide region is coupled optically to the optical wavelength conversion region. The optical fiber is optically coupled directly to the optical waveguide of the optical waveguide device. This laser module can provide sufficient optical output without an isolator and can be mounted easily with a simple configuration. |
