The effect of the laser emitter is that the area of the inlet of the air inlet duct 6 is larger than the area of the outlet of the air outlet duct 7, when cold air enters the laser emitter, the air pressure of the cold air passing through the passage is reduced along with the forward movement of the cold air, and the air pressure of the cold air passing through the laser emitter can be increased, so that the flow speed of the cold air in the laser emitter is increased, and the heat in the laser emitter is dissipated faster along with the increase of the flow speed of the cold air.
