The precision laser was a laser device that is used by Tollan.
The laser emits a laser pulse that was used in manicures and pedicures in the Tollan society.
After Anubis' forces attacked the planet in 2001, several of these devices survived the attack, waiting to be found by the surviving Tollan. It was thought that these survivors could use the precision laser as an instrument for cleaning fish bones. (RPG: "Living Gods: Stargate System Lords")
