PURPOSE: A laser emitter interworking with a portable device is provided to share the battery of the chargeable portable device, thereby recycling resources and reducing environmental pollution. CONSTITUTION: A laser emitter comprises a main body (101) comprising laser emitter control circuit, a connection part (103), and an application (102) for control of the laser emitter control circuit. The connection part is connected to a portable device (100) to transmit electricity from a rechargeable battery (104) included in the portable device to the main body. The application transmits a signal to the laser emitter control circuit included in the main body to turn on or off a laser emitter and control the intensity or color of the laser. |
