| 英文摘要 | A laser-driven interferometric signal sensing system has a cleaved-coupled cavity laser with separate stabilization servo loops of different time constants for the modulator and laser sections thereof. The laser section is biased above lasing threshold, and its stabilization loop is operated at a frequency twice the frequency of laser section bias current modulation. A laser loop feedback error signal is a function of predetermined, environmental-type, parameter variations in the sensing location and is processed to be a function of the second derivative of interferometer output intensity with respect to laser section current. That error signal is applied to modify laser section bias current in a direction to zero out the feedback signal. |
