Bob, some years ago I serviced a few "Lasertronic" units.
Whether the name is coincidental and means anything or
not I can't say, but here's the system they used

When the trigger is pulled, three 220ms bursts are sent

Each 220ms burst is - 100ms plain 26.2kHz, 60ms of
gun ID, 60ms gun ID. The gun ID is broken down as -
quiet for 10ms, then a 5-bit ID, each bit either 10ms of
26.2kHz or quiet

The transmitting diode is a TOLD9211 IR laser. The first
units I looked at had a 68HC705P2 in the gun and jacket
and an 8031 in the base station. Just before the place
moved out of town they were introducing new units with
16C84s in the gun and jacket
