Abstract
This invention comprises an optically pumped iodine monofluoride laser operating on the B.sup.3 .pi.(0.sup.+).fwdarw.X.sup.2 .SIGMA..sup.+ system. Ground state IF was produced by the reaction between I.sub.2 and F.sub.2 in an optical cavity which was subsequently optically pumped with a high energy, broadband dye laser to produce lasing energy.
Claims4
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.

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.
