摘要
A strain and temperature-sensing scheme based on a dual-wavelength fiber laser is demonstrated experimentally. By measuring the change in the wavelength separation of the two lasing wavelengths and the shift of any of two lasing wavelengths, the measured strain and temperature are very linear and have a strain sensitivity of 0.15 pm/mu epsilon over a range of 0-2400 mu epsilon and a temperature sensitivity of 14.3 pm/degrees C over a range of 22 degrees C-230 degrees C, respectively.
