Phenomenon of Laser Wavefront Intermittently Distortion Induced by Adjustment of the Resonant Cavity Length
The phenomenon of laser wavefront intermittently distortion induced by periodically adjusting the resonent cavity length of a CO 2 laser was observed. It leads to the signal discontinuity of a coherent FM CW laser radar. The preliminary analyses indicate that this phenomenon is connected with the laser branch line. When this distortion occurs, the laser branch line doesn′t shift and the microscopic characteristics of the transverse mode have no change.
