Dustin Brown scored twice during the Kings' three-goal first period, and Carter had three points in Los Angeles' sixth straight home victory over Ottawa in the past decade.
Milan Michalek scored the tying goal with 4:27 left in regulation for the Senators. Jean-Gabriel Pageau netted his third career goal in the second period, and Bobby Ryan scored his first goal with Ottawa early in the third.
