(a) The shift rate of the 1535 nm lasing WGM as function of input pump power for different gas flow rates. (b) The calculated increase in cavity temperature and corresponding WGM shifts. (c) The shift of the 1535 nm lasing WGM as function of the measured flow rate for different pump powers, solid lines are fits. (d) The sensitivity of the WGM shift rate as function of measured flow rate, calculated from the derivative of the, solid lines are fits in (c).
