    keyword=The changed is due to slightly increase in the pumping cell temperature

    Because of the strong absoption of the cell, very small portion of the COMET laser will pass through the cell and be seen by the spectrum analyzer. So a slightly increase in the pumping cell, 1 to 2 degrees, will make spectrum significantly lower. Please also post the oven strip chart including the oven temperature and two RTDs.
