Observation of photon echoes using a nitrogen laser pumped dye laser

Photon echoes have been observed using a nitrogen laser pumped dye laser as the excitation source. The echo was obtained in the 3H4\u21923P0 transition in Pr3+:LaF3. The dependence of echoes on magnetic field and temperature was measured.The authors were affiliated with the National Research Council of Canada, Radio and Electrical Engineering Division when they authored this article.Les auteurs \ue9taient affili\ue9 avec le Conseil national de recherches du Canada, Division de la radio et du g\ue9nie \ue9lectrique lorsqu\u2019ils ont r\ue9dig\ue9 cet article.Peer reviewed: YesNRC publication: Ye
