Joseph Cordes, 42, of Winthrop, Mass., will be charged with disturbing the peace, police said Tuesday.
He is accused of pointing the light at a high school goalie from the Medway-Ashland team last Wednesday.
Cordes said he feels like a jerk.
"I wish I could undo it," Cordes told WBZ-TV, Boston. "I feel like a complete jerk. It was very stupid, completely immature for a 42-year-old man to be doing that."
Winthrop won the game 3-1.
The goalie Kathryn Hamer said the laser made it hard to focus on the game. "It's kind of like when you look at the sun and then you look away you see that spot and you can't see for a couple of seconds," Hamer told WBZ.
