Clark Gable III, 22, had pleaded guilty to shining a laser light at the aircraft that was flying above Hollywood Boulevard on July 28.
Gable was very apologetic in court, telling Judge David Horwitz he was sorry and learned a good lesson.
Officials said the green laser obstructed the vision of the two officers in the chopper. LAPD officers Glen Plahy and Mike Rodriguez, who were flying the helicopter, appeared in court to state that pointing a laser beam at an aircraft is very dangerous and a serious thing.
"It's very honorable for Mr. Gable to take, to admit responsibility for this situation," Rodriguez said.
After the sentencing hearing, Gable said he wasn't really thinking when he pointed the laser at the helicopter.
"My friend had just bought a new car, and we were driving around. I wasn't really thinking when I pointed the laser beam at the helicopter," he said.
Gable will begin his sentence at the Glendale Jail on Jan. 27. He has paid $570 in restitution and will have to complete 200 hours of Caltrans. He was placed on a formal probation for three years.
