High power laser system
View Patent ↗A modulation device for directing a mobile tracking device away from an asset is provided. The modulation device includes a continuous wave laser source whose output is directed at a seeker head of the mobile tracking device. The modulation device causes the generation of localized sources within the mobile tracking device and confuses the mobile tracking device as to the true location of the asset. A portable cutting device is disclosed. The portable cutting device may include a portable power supply and a laser source. The portable power supply and laser source of the portable cutting device may be positioned within a backpack and carried by a user. A handheld unit which is coupled to the laser source may be supported by the hands of the operator. The handheld unit provides power generated by the laser source to a barrier to be cut.
1. A portable cutting device for transport by a human operator, comprising:
a laser source which provides optical energy, the laser source being a plurality of continuous wave semiconductor lasers whose output is combined to provide the optical energy;
a battery power source;
a laser directing device supporting focusing optics in a collimating chamber, the focusing optics focus the optical energy provided by the laser source;
at least one storage container, the at least one storage container housing the laser source and the battery power source; and
at least one flexible optical conduit extending from an interior of the at least one storage container to the laser directing device, the at least one flexible optical conduit communicating the optical energy produced by the laser source to the laser directing device;
wherein the at least one storage container includes a backpack which includes a cargo carrying portion housing the battery power source and the laser source and support straps through which arms of the human operator extend.
2. The portable cutting device of claim 1 , wherein the plurality of continuous wave semiconductor lasers are quantum cascade lasers.
3. The portable cutting device of claim 2 , wherein a power level of the optical energy provided by the laser source is at least 3 kilowatts.
4. A portable cutting device for transport by a human operator, comprising:
a laser source which provides optical energy, the laser source being a plurality of continuous wave semiconductor lasers whose output is combined to provide the optical energy;
a battery power source;
a laser directing device supporting focusing optics in a collimating chamber, the focusing optics focus the optical energy provided by the laser source;
at least one storage container, the at least one storage container housing the laser source and the battery power source; and
at least one flexible optical conduit extending from an interior of the at least one storage container to the laser directing device, the at least one flexible optical conduit communicating the optical energy produced by the laser source to the laser directing device;
wherein the laser directing device includes a controller, a trigger, a compressed air container, a valve in fluid communication with the compressed air container, and a nozzle directed at a focus of the focusing optics and in fluid communication with the valve.
5. The portable cutting device of claim 4 , wherein the valve is opened by the controller based on a status of the trigger to provide an air stream generally towards the focus of the focusing optics.
6. The portable cutting device of claim 4 , wherein the laser directing device further includes a second fluid conduit in communication with the valve and in fluid communication with the collimating chamber, the controller controlling the valve to provide air from the compressed air container to the collimating chamber.
