Water-guided laser water jet power measuring device

The utility model belongs to the technical field of laser cutting processing, and relates to a water-guided laser water jet power measuring device which comprises a power measuring shell, a power measurer measuring part, a negative lens and an optical filter. Meanwhile, converged laser beams are refracted and diverged and then irradiated to the bottom of the mortar-shaped inner cavity of the water-free power measuring shell, the water-free diverged laser is measured by the measuring part of the power measurer, the safety and the precision of laser measurement are guaranteed, and the laser water jet power measuring device is safe and convenient to use. Tedious steps of manual measurement are avoided, the laser burn risk is reduced, meanwhile, damage protection is conducted on the power meter, measurement is more accurate and reliable, and operation is safer and more convenient. 本实用新型属于激光切割加工技术领域,涉及一种水导激光水射流功率测量装置，包括：功率测量壳体、功率测量器测量部、负透镜、滤光片，通过负透镜将激光水射流中的激光和水分离，同时将汇聚激光束折射发散后照射在无水的功率测量壳体臼型内腔底部，由功率测量器测量部对无水且发散后的激光
