A new energy transfer chemical laser at 1.315 μm

Recent Progress in the Development of a Multi-Watt All Gas-phase Iodine Laser (AGIL)

“…The Cl / HN 3 stoichiometry suggests that the optimum 28 condition for NCl(a'A) production is HN 3 = 0.5C1 = NF 3 , and our result is a factor of 2 too -4-American Institute of Aeronautics and Astronautics large. This is not a surprising result considering that Herbelin 24 and Henshaw 23 reported a very similar trend for AGIL 1. Their optimum F : HN 3 ratios for gain/lasing power were 2.3 and 1.9, respectively.…”

“…Indeed, a subsonic, continuous wave, chemical I*( 2 Pi/2> laser pumped by NCl(a'A) was reported by Henshaw and co-workers in 2000 23 . The authors named their discovery the All Gas-phase Iodine Laser, or AGIL.…”

The Measurement of Gain in a Supersonic, Combustion-Driven Generator for NCl(a1Delta)

“…for example, produced a supersonic flow with T = 400 -500 K. According to temperaturedependent rate constant measurements and the previous subsonic AGIL work [1,24], this is nearly optimal for NCl(a A second challenge for future AGIL devices is tied to the laser fuel, HN 3 . Because of its potential (some would say propensity) for explosive decomposition, the storage and dynamic pressure of HN 3 must be kept low.…”

“…All reagent and diluent flow rates except for HN 3 were controlled by Proportion Air electronic gas pressure regulators (Model #QBIT-FEE-500) and calibrated sonic orifices. Table 1.…”

“…The first continuous wave AGIL device, demonstrated by Henshaw in 2000 [3], was enabled and inspired by the work of many, including Benard [9], Bower [10,11], Clyne [12][13][14], Coombe and Gilbert [15][16][17][18][19], Heaven [7,20,21], Henshaw [22,23] …”
