3. Amplify the Beam
The optical resonator bounces this light between mirrors, forcing more iodine molecules to cough up their photons, further increasing the laser beam's intensity. From there, the light travels through a sealed pipe above the weapon's crew station and into a chamber called the optical bench. There, sensors determine the beam's quality, while mechanically controlled mirrors compensate for movement of the airplane, vibration and atmospheric conditions. Precise airflow regulates the chamber's temperature and humidity, which helps keep the beam strong.
