Abstract
Abstract CW laser action achieved on the 2P 178- 2P 3/2 transition of the iodine atom by energy transfer from the 1 Δ metastable state of O 2 . The effluent from a conventional oxygen generator was mixed with molecular iodine at the entrance of a longitudinal flow laser cavity where the I 2 was dissociated by a small amount of O 2 ( 1 Σ) that was present in the flow due to energy pooling processes. The measured output power was greater than 4mW.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
102 words
A method for producing a continuous wave, chemically pumped lasing action which comprises: A. providing a resonant cavity having oppositely disposed reflecting means; B. continuously introducing a stream of gaseous molecular oxygen in the singlet-delta electronic state into said cavity; C. admixing a continuous flow of gaseous molecular iodine with said stream of oxygen to form an electronically excited, continuously flowing, gaseous mixture; D. passing said flowing, excited gaseous mixture through said resonant cavity to produce a beam of coherent electromagnetic radiation; and E. continuously exhausting said oxygen and iodine gasses at the end of said resonant cavity subsequent to their mixing.
Claim 2
Independent Claim

Claim 3
Dependent Claim
29 words
A method in accordance with claim 1 wherein said molecular iodine is admixed at a point just ahead of the entry of said gaseous oxygen into said resonant cavity.
