Experimental Study on Combustion-driven Hydrogen Bromide (HBr) Chemical Laser

An experimental study of combustion-driven HBr chemical laser based on D-2/NF3 combustion was carried out. The exotherm of the reaction system was analyzed, and the thermal blockage issue of supersonic flow was solved by adjusting the buffer coefficient.. By optimizing the laser operating conditions, a maximum HBr laser output of 141W was obtained, with the primary laser lines being HBr P-1(5), P-1(6), and P-3(6).
