1. A laser transmission device for use with a firearm to simulate firearm operation in response to actuation of said firearm by a user comprising:

  • a housing configured in the form of a firearm cartridge for placement within a firing chamber of said firearm and including;

    a power source;

    a laser transmitter;

    a sensor to detect actuation of said firearm and produce an actuation signal in response thereto;

    a laser modulation unit responsive to said actuation signal to apply a modulation signal of a specific frequency to a laser signal of said laser transmitter to emit a modulated laser pulse compatible with an intended target responsive to laser signals modulated at said modulation signal frequency; and

    an optics module to direct said emitted laser pulse from said housing toward said intended target in a substantially concentric fashion relative to a barrel of said firearm absent alignment of said device with a firearm bore sight.
