Abstract
We propose a sensor based on the temperature dependant behavior of the two lines of green emission of the erbium ion, The ratio of the inten sities of these two lines presents a very low dependance on pump wavel ength and pump power fluctuations, The sensitivity of the ratio is 0.0 13/degrees C between room temperature and 600 degrees C. In addition, the measurement is self-calibrated.
