New method for detecting transient gain /or loss/ in pulsed gas discharges
Abstract
A pulsed argon discharge inside a cw-laser cavity is used to modulate the cw-laser output via the transient gain/loss at various lasing wavelengths. Under short-pulse excitation (about 0.6 microsec), gain is found at four Ar(II) lasing lines, but losses are observed at 4880 and 5017 A. A similar diagnostic device with broad-band capabilities and based on an ion-laser-pumped dye laser is proposed.
