Abstract
Abstract This invention comprises an optically pumped iodine monofluoride laser operating on the B 3 π(0 + )→X 2 Σ + system. Ground state IF was produced by the reaction between I 2 and F 2 in an optical cavity which was subsequently optically pumped with a high energy, broadband dye laser to produce lasing energy.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
An optically pumped laser system which comprises: (A) a resonant cavity bounded by a substantially totally reflective mirror and a partially transmissive mirror; (B) nozzle means for directing a first molecular iodine gaseous reactant and a second molecular fluorine gaseous reactant into said resonant cavity to produce an iodine monofluoride lasing medium in the form of a non-stable, chemiluminescent, reaction product; and (C) a source of optical pumping energy positioned to direct an energy beam of electromagnetic energy at said lasing medium to effect its population inverson and thereby produce laser energy.
Claim 2
Dependent Claim
92 words
An optically pumped laser system which comprises: (A) a resonant cavity bounded by a substantially totally reflective mirror and a partially transmissive mirror; (B) nozzle means for directing a first molecular iodine gaseous reactant and a second molecular fluorine gaseous reactant into said resonant cavity to produce an iodine monofluoride lasing medium in the form of a non-stable, chemiluminescent, reaction product; and (C) a source of optical pumping energy positioned to direct an energy beam of electromagnetic energy at said lasing medium to effect its population inverson and thereby produce laser energy.
Claim 3
Dependent Claim
18 words
A laser system in accordance with claim 1 wherein said pumping source comprise a tunable pulsed dye laser.
Claim 4
Dependent Claim
57 words
A laser system in accordance with claim 1 wherein said nozzle directing means comprises a centrally located nozzle for delivering said first gaseous reactant in a predetermined direction and further includes a pair of conduits each disposed on an opposite side of said centrally located nozzle for delivering said second gaseous reactant in the same predetermined direction.
Claim 5
Independent Claim
100 words
A method for producing an optically pumped beam of coherent electromagnetic radiation which comprises the steps of: (A) providing a resonant cavity; (B) introducing a flow of a first molecluar iodine gaseous reactant and a second molecular fluorine gaseous reactant into said resonant cavity. (C) mixing said first and second gaseous reactants to effect a chemical reaction therebetween and produce a nonstable, chemiluminescent, iodine monofluorine, reaction product; and (D) directing a source of optical pumping radiation as an excitation source at said chemiluminescent, iodine monofluoride, reaction product to effect its population inversion thereby producing said beam of coherent electromagnetic radiation.
