This creation is a kind of laser repelling device, what is set at an entrance, the laser repelling device includes laser mould group, driving device and arrangement for detecting, driving device can be directed to entrance to the laser light ray for generating laser mould group, and what entrance forms the laser light ray of dynamic scan, to mosquito expelling. Arrangement for detecting can be to detect the biological close to entrance of non-mosquito, to stop the running of laser mould group.本創作為一種雷射驅除裝置，設置於鄰近一出入口處，該雷射驅除裝置包括雷射模組、驅動裝置及偵測裝置，驅動裝置能用以將雷射模組產生的雷射光線導引至出入口，並於出入口形成動態掃描的雷射光線，用以驅除蚊蟲。偵測裝置能用以偵測非蚊蟲的生物靠近出入口，用以停止雷射模組的運作。
