| Abstract: | The design principle and circuit structure about the laser power supply with fixed output power and improved power factor is presented in this paper.The output power of this laser power supply cannot be changed as the line voltage is shifted.So this laser power supply may make the output laser energy less in stable.Moreover,the laser power supply with improved power factor might effectively restrain the harmonic noise and reduce the input ampere-capacity of power equipment and so on. |

| Keywords: | output power power factor switching power supply laser |
