Successfully developed a high-energy explosives pumping photolysis iodine laser system to achieve a stable laser output of the explosion laser device and obtain nearly one hundred joules of the laser output energy were measured in the experiment 101.325 kPa argon under the impact of the shock wave front radiation Spectrum and the propagation velocity of the shock wave front.The explosion laser system uses the heptafluoropropane propane C3F7I as the laser working substance and the high energy explosive as the pumping energy, and obtains the better explosion laser waveform in the experiment. The laser pulse width (full width at half maximum FWHM) is about 34μs, the minimum beam divergence angle is less than 20 mrad.The working principle of the explosion laser is introduced in detail, and the specific experimental device and experimental technology are analyzed and described.Explosive laser experiments are carried out under different experimental conditions The experimental results were analyzed and the factors affecting the laser output were analyzed and discussed, which laid the foundation for the further development of the explosive laser device with larger energy.
