Summary:Disclosed is a 2490nm and 1208nm double-wavelength optical-fiber output laser for ocean exploration, an overall light path is set to be in an S type, a signal light 2490nm four-wave mixing periodically polarized lithium niobate laser resonant cavity is disposed, a pump light I 1208nm beam splitting optical-fiber ring is disposed on a pump light I 1208nm transmission optical fiber, signal light 2490nm, idler frequency light 915nm, pump light I 1208nm and pump light II 1550nm go into the signal light 2490nm four-wave mixing periodically polarized lithium niobate laser resonant cavity, a four-wave mixing effect occurs, a signal light 2490nm output is generated, and 2490nm and 1208nm double-wavelength optical-fiber laser is finally output.
