It is highly important to clarify the basic characteristics of plasmas produced by laser focusing for investigating the possibility of laser-induced lightning. This paper reports the electron density, electron temperature and neutral particle density in laserinduced plasmas measured by Thomson and Rayleigh scattering techniques. The electron temperature increases to 2.5eV in maximum in 3 to 3.5μs after firing the laser, and then gradually decreases in several tens of microseconds. The Rayleigh scattering measurement has shown that the rarefied air region of lower neutral particle density takes a spherical shell profile in later stages after the laser firing. This has been also confirmed by the induced discharge paths through the circumference of a plasma after 500μs.

An educational project for promoting the practical professional engineers has been carried out using a special fund from the Ministry of Education (MEXT) , since the fiscal year 2005 after five sixths of the departments were accredited from JABEE. Some typical activities of the project such as design education for the mechanical engineering, motivating self-directed learning for the chemical engineering, and a small-size class for the electrical engineering are described.
