Experimental Study on Supersonic All Gas-phase Iodine Laser Driven by NF_3/D_2/DCl/CF_3I Combustion

摘要

A supersonic all gas-phase iodine laser driven by NF_3/D_2/DCl/CF_3I combustion has been experimentally studied, the gain signals of I(~2P_(3/2),F=4)← I(~2P_(1/2),F=3) at 1315.246nm and I(~2P_(3/2),F=3)← I(~2P_(1/2),F=3) at 1315.222nm were observed with an intensity of 3×10~(-5)cm~(-1) and 1×10~(-5)cm~(-1) respectively. The small signal gain of I(~2_(P3/2),F=4)← I(~2P_(1/2),F=3) at different location relative to HN3 injector along the flow direction also was obtained. The experimental results indicate that the AGIL driven by NF3/D2/DCI/CF3I combustion is feasible.
