Laser energy emission system

A laser energy emission system comprises a laser, a dichroic spectroscope, a fast reflecting mirror, a collimator, a beam expander, an imaging device, a control system, a computer, a first reflecting mirror, a second reflecting mirror, a holder and a target surface with a beacon light source. The fast reflector and the holder are respectively connected with the control system, and the imaging system and the control system are respectively connected with the computer. By means of the device, the beacon light enters the imaging system through the internal light path, and the center position of the target surface is obtained. The computer controls the holder and the fast reflector to rotate to track the center of the target surface, and the light beam irradiates. A traditional laser emission system is limited by pan-tilt bearing, sensor response time and image definition, and therefore the tracking speed and precision are affected. According to the invention, a laser energy emission system is designed, and the a
