Topic: Ablative Laser Propulsion
Speaker: Andrew V. Pakhomov, UAH
Date & Time: Thursday, October 30, 2003, 1:00 PM
Place: Room 140 VMC (Chambers Hall)
Although the first directed delivery of energy over a distance by focused light was successfully demonstrated 22 centuries ago, only relatively recent invention of laser (1960) opened new horizons in this field. The modern history of Laser Propulsion (LP) started in 1972, when Dr. Arthur Kantrowitz (Avco-Everett Labs) first popularized the idea of using ablation of matter under intense laser fields for space transportation. Over passed thirty years LP has evolved from a simple vision of somehow using a remote laser to transmit energy to spacecraft in flight, into a demonstrated propulsion technology. In this talk the physical principles of laser propulsion as well as currently existing and developing LP schemes and their applications will be reviewed. The main discussion will be devoted to ablative laser propulsion, the concept proposed by Dr. Pakhomov and currently developing by Laser Propulsion Group at UAH.
Dr. Andrew V. Pakhomov is an Associate Professor at the Department of Physics, UAH, where he works since 1998. He graduated from Michigan Tech University in 1996 with Ph.D. in Physics and specialization in laser-induced plasmas and laser spectroscopy. He also holds M.S. degree in materials science, which he received in 1983 from Moscow Technological University. Dr. Pakhomov has over 70 scientific publications, two patents and one book in the field of laser-induced plasmas (laser propulsion, ion dynamics, spectroscopy, high-field laser-matter interactions) and physics/materials science of semiconductors. Currently he concentrates his research in the field of laser-matter interactions, where his mostly recent topic of study is ablative laser propulsion (ALP). In 2002 he proposed, organized, and co-chaired the First International Symposium on Beamed Energy Propulsion, which took place in Huntsville, in November 2002.
