Abstract :
Laser power stabilization for a chemical oxygen-iodine laser (COIL) was demonstrated using a complete feedback system with an external magnetic field based on the Zeeman effect of the iodine transition. The input/output characteristics of the feedback system are theoretically analyzed and found to be consistent with the experimental results. As a result, highly stable output power of less than 0.4% rms fluctuation was successfully obtained even in the presence of disturbance associated with mechanical vibration. It was also found that the response time of the system was as short as 1 ms limited by the applied voltage of the electromagnet
