Abstract

According to the requirement of system，an one-dimensional beam shaping system is designed for semiconductor laser. In this beam shaping system, we choose an aspheric cylindrical mirror as the shaping element. To design the aspheric cylindrical mirror, we first calculate the incipient structure and then use the software light tools to optimize and simulate. The result shows that for a semiconductor laser whose beam diverging angle is 40°, the diverging angle will smaller than 1mrad after shaping by the aspheric cylindrical mirror. Also, we test the actual beam shaping system and the result shows that it meets the requirement of system well.
