Research output: Contribution to journalArticlepeer-review


Lasing on 11 transitions of neutral iron (six of which have not been reported previously) is observed when iron diiodide (FeI2) is photodissociated at 193 nm (ArF laser). The lasing wavelengths span the visible spectrum, extending from 466 to 794 nm. Although the maximum laser energy output of ∼1µJ (all lines) occurs at ∼825 K, stimulated emission is observed for temperatures as low as 720 K.
