Phase-matching free pulse retrieval based on plasma-induced defocusing [PDF]
EPJ Web of Conferences, 2023 A phase-matching free pulse retrieval technique based on plasma-induced defocusing in a rare gas is presented. Based on a pump-probe setup, this technique uses a moderately intense pump laser pulse for ionizing the medium, creating in turn an ultrafast ...

Asymmetric quantum well far infrared lasers [PDF]
, 1999 In recent years, because of the availability of high quality quantum well (QW) wafers grown by MBE (molecular beam epitaxy) and MOCVD (metallic organic chemical vapour deposition) techniques, QW lasers have developed rapidly. This has led to the rapid development of mid infrared MQW lasers, in particular the cascade lasers and optically pumped "quantum
