Abstract

A laser weapon system is described. Particularly, embodiments describe subsystems of a laser weapon system including those necessary for laser generation, operational control, optical emission, and heat dissipation configured to provide a lightweight unit of reduced dimensions.

First claim

Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1 . A laser weapon system configured to be coupled to a firearm, the laser weapon system comprising:
a portable body configured to be carried by a user, the portable body comprising:
a laser generation module configured to generate a laser, the laser generation module coupled to a power source that powers the laser generation module; and
a heat mitigation module configured to cool the laser generation module;
a laser emitting unit configured to be mounted to a portion of the firearm; and a fiber optic cable coupled at a first end to the laser generation module and at a second end to the laser emitting unit, the fiber optic cable configured to transmit the laser generated by the laser generation module to the laser emitting unit.

2 . The laser weapon system of claim 1 , wherein the laser emitting unit comprises a cylindrical body configured to be mounted at a side of the firearm.

3 . The laser weapon system of claim 2 , wherein the laser emitting unit is configured to be aimed using a sighting scope of the firearm, and wherein the laser weapon system is configured to be operated by an activation mechanism disposed on the firearm.

4 . The laser weapon system of claim 1 , wherein the portable body is configured to be disposed within a backpack worn by the user.

5 . The laser weapon system of claim 1 , wherein the heat mitigation module comprises:
one or more pumps configured to pump a cooling fluid through the portable body.

6 . The laser weapon system of claim 1 , wherein the heat mitigation module comprises one or more cooling pods including a phase change material disposed therein, the phase change material configured to absorb heat from the laser generation module such that the phase change material is at least partially melted.

7 . The laser weapon system of claim 6 , wherein the one or more cooling pods are removable from the portable body.

8 . A laser weapon system comprising:
a laser emitting unit configured to be attached to a firearm, the laser emitting unit comprising:
a cylindrical body; and
one or more focusing lenses disposed in the cylindrical body; and
a fiber optic cable coupled to the laser emitting unit, the fiber optic cable configured to transmit a laser generated by a laser generation module to the laser emitting unit.

9 . The laser weapon system of claim 8 , wherein the one or more focusing lenses comprises a first lens and a second lens.

10 . The laser weapon system of claim 9 , further comprising:
a cable terminus disposed in the cylindrical body, the cable terminus configured to receive the fiber optic cable.

11 . The laser weapon system of claim 10 , further comprising:
a focusing knob disposed on an external portion of the cylindrical body, the focusing knob configured to adjust a distance between the cable terminus and the first lens.

12 . The laser weapon system of claim 11 , further comprising:
a baffling portion disposed in the cylindrical body that reduce stray light emissions from the laser emitting unit.

13 . The laser weapon system of claim 8 , further comprising:
an inclinometer configured to detect an angle of the laser emitting unit.

14 . The laser weapon system of claim 8 , wherein the laser emitting unit is configured to be removably attached to a rail of the firearm.

15 . A laser weapon system configured to be coupled to a firearm, the laser weapon system comprising:
a portable body configured to be carried by a user, the portable body comprising:
a laser generation module configured to generate a laser; and
a heat mitigation module configured to cool the laser generation module;
a laser emitting unit configured to be mounted to a portion of the firearm; a fiber optic cable coupled at a first end to the laser generation module and at a second end to the laser emitting unit, the fiber optic cable configured to transmit the laser generated by the laser generation module to the laser emitting unit; and a control module communicatively coupled to the laser generation module, the control module configured to control operation of the laser generation module.

16 . The laser weapon system of claim 15 , wherein the control module comprises:
a hand-held body that is physically separate from the portable body; one or more input controls; and a display portion.

17 . The laser weapon system of claim 16 , wherein the control module is operable to adjust an operation mode of the laser weapon system responsive to an operator input to the one or more input controls.

18 . The laser weapon system of claim 15 , wherein the portable body comprises a backpack.

19 . The laser weapon system of claim 18 , further comprising:
a power source disposed in the backpack that provides power to the laser generation module.

20 . The laser weapon system of claim 19 , wherein the power source comprises a removable battery.
