Abstract
An enhancement of ∼100 of stimulated emission over spontaneous emission of the C v i 182-Å line (one-pass gain ∼6.5) was measured in a recombining, magnetically confined plasma column by two independent techniques involving intensity calibrated extreme xuv monochromators. Additional confirmation that the enhancement was due to stimulated emission has been obtained with a soft x-ray mirror; with 12% measured effective reflectivity of the mirror, a 120% increase in intensity of the C v i 182-Å line in the axial direction was observed.Keywords
