    To research the recoverey pressure of DF laser, experiments were carried out with different mass flowrate on a test bench. Thermal blockage was discovered when the mass flowrate reached 2.475 g·s-1·cm-2. The simulation model of laser cavity and diffuser was established, and the flow fluid was obtained. The simulation showed that the cavity’s pressure rose up quickly when the mass flowrate was 2.475 g·s-1·cm-2, which is coincident with the experiment. The design was optimized based on the result of the simulation and the corresponding experiment was proceeded. The result shows that the thermal blockage was solved with the optimized laser cavity. The laser’s recovery pressure reached 22 kPa with mass flowrate 2.475 g·s-1·cm-2.
