How to Sign "Later" in American Sign Language (ASL)
Dominanting "L" hand held in side space rotates forward once or twice, depending on the contexts. People use it a lot in everyday talks, mainly when saying goodbye or setting up plans. The movement can be done more carefully to make it formal, or you can add time words to be more clear. When you want to say "see you later," you do the signs for "see" and "you" with it.
