Abstract: Proposed is a portable laser weapon. The portable laser weapon includes: a laser generation unit generating a high-power laser beam; a wearing unit having the laser generation unit therein and being able to be worn on an individual; a sighting-shooting unit receiving and shooting a laser beam generated from the laser beam generation unit; and a beam transmission cable connecting the laser generation unit and the sighting-shooting unit to each other, thereby transmitting a laser generated from the laser generation unit to the sighting-shooting unit. Accordingly, it is possible to considerably improve the usability of laser weapons by providing a laser weapon that can be operated by an individual infantryman and can shoot a high-power laser.
