Experimental study on an all gas-phase iodine laser using microwave discharge of Cl2/He as a Cl atoms source.
Microwave discharge of a Cl2/He mixture as a simple, clean and efficient Cl atom generator was used for an all gas-phase iodine laser study. Sufficient NCl(a1Delta) was produced through the reaction of HN3+2Cl-->NCl(a1Delta)+HCl+N2. The energy transfer reaction of I(2P3/2)+NCl(a1Delta)-->I(2P1/2)+NCl(X3Sigma) was observed. A population inversion was observed directly by using a 1315 nm tunable diode laser by scanning the entire line shape of the (3,4) hyperfine transition of iodine, and a small signal gain of 5x10(-5) cm-1 was obtained.
Experimental study on supersonic all gas-phase iodine laser driven by NF3/D2/DCl/CF3I combustion
A supersonic all gas-phase iodine laser driven by NF3/D2/DCl/CF3I combustion has been experimentally studied. the gain signals of I(2P3/2,F=4)← I(2P1/2,F=3) at 1315.246nm and I(2P3/2,F=3)← I(2P1/2,F=3) at 1315.222nm were observed with an intensity of 3x10-5cm-1 and 1x10-5cm-1 respectively. The small signal gain of I(2P3/2,F=4)← I(2P1/2,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/DCl/CF3I combustion is feasible.
Energy
Energy is often defined as the ability to do work. There are many forms of energy. A few examples include; Gravitational energy, Kinetic energy (energy of motion), Thermal energy (heat energy), Potential energy. Potential energy is the energy something has based on its position in the universe. A stretched elastic band has potential energy. A rock held up in the air has potential energy based on its position.
