Abstract
The present application provides a multi-wavelength laser for synchronously monitoring the temperature and pressure of an ocean. A pulse controller is used to convert a broadband laser outputted by a broadband laser source into a broadband pulsed light, and then a phase shifted fiber bragg grating unit is used to demodulate a plurality of pulsed light with different wavelengths from the broadband pulsed light. The pulsed light outputted by the laser is emitted into a sensing fiber in seawater via a wavelength division multiplexer, scattered light is returned to a control demodulation module via the wavelength division multiplexer, the control demodulation module demodulates the scattered light, so that the dynamic pressure is parsed according to a phase change of a light signal, and the seawater temperature is parsed according to a wavelength change of the light signal.
