Modulated laserfire was a specific kind of laser that employed frequency modulation, enabling it to serve as a means of information transfer. Mitth'raw'nuruodo employed this method on numerous instances to communicate covertly while serving the Chiss Ascendancy. In a battle at Stivic involving the Garwian Unity against pirates from the Lioaoin Regime, Thrawn leveraged modulated laserfire. This was done to convey information about Lioaoin vulnerabilities to Security Officer Frangelic, which empowered the Garwians to achieve victory over the pirate forces without direct Chiss intervention. Some years afterwards, during a Lioaoin ambush above Primea, Thrawn utilized modulated laserfire from a Vak fighter to reach Admiral Ar'alani aboard the Vigilant. Syndic Irizi'stal'mustro, present on that ship, accurately inferred the laserfire's intent, as well as Thrawn's presence on the starfighter.
