The invention discloses a LabVIEW-based integrated femtosecond laser micro-nano machining system and method. According to the LabVIEW-based integrated femtosecond laser micro-nano machining system and method, a DLL dynamic depot of a PMAC motion control card is called through a LabVIEW programming environment, so that the PMAC control card connected with a computer by way of Ethernet is driven, precision control over a high-precision three-dimensional mobile platform unit is achieved indirectly, and display on a software interface is achieved; meanwhile, the state, monitored through a high-definition CCD camera, of a sample processed through femtosecond laser and processing process data are transmitted to control software and displayed in real time through USB communication; and in addition, femtosecond laser power parameters are collected in real time, the make-and-break state of femtosecond laser beams is controlled, multi-threading control programs are developed through LabVIEW, and multi-controller software different in communication mode is developed in an integrated manner. The system has the beneficial effects of being high in adjustment precision, high in speed, easy to adjust, low in control difficult and diversified in interface function; and manufacturing work of multiple types of micro-nano structures can be achieved.
