A Laser Communicator is a technological device for sending and receiving signals and messages.

Description / Specifications[edit]

A laser communicator is an optical communicator in which the light source is a laser whose beam is modulated for voice, video, or data communication over wide information bandwidths.

  • A laser communicator is an Active device.
  • Laser communicators transmit a tight beam signal.
  • A laser communicator is a line of sight device.
    • The transmitter must know the precise position of the receiver in order to conduct communications.
  • Laser communicators receive transmissions via a Laser Sensor receiving array.
    • Transmissions can be disrupted or blocked by intervening terrain such as weather systems, mountains, stars and Sandcaster clouds.
    • Prismatic aerosols specifically block lasers, including laser communications.

History & Background / Dossier[edit]

Laser Communicators are available from TL-8 onwards.

The power of a laser communicator determines its effective broadcast range – the distance to which a signal beam will carry before it is sufficiently degraded to be indistinguishable from natural background noise and static.

  • Small portable laser communicators are available. They are usually equipped with tripods or other stabilization gear.
  • Larger laser communicator systems may be fitted aboard vehicles and spacecraft, with effective beam transmission ranges measured in millions or even billions of km.

A laser communicator is limited by realspace physics. The laser beam that the device produces takes time to reach its target.

  • A beam travels at approximately 300,000 km per second. For example, a laser communicator attempting to conduct a conversation with a target at a distance of 3 million km will have a signal delay of 10 seconds (10 seconds for the laser beam to reach the target).

Devices almost identical to Laser Communicators in function have applications in security, construction, surveying and a range of other industries.
