DIDACTICAL N-2 LASERS

This work presents the design, construction and parameterization of Ni trogen lasers, which are easy to build by undergraduate students. Thes e are transversal discharge lasers at atmospheric pressure (TEA), exci ted by a Blumlein circuit, emitting nanosecond pulses in the ultraviol et region of the spectrum (lambda = 337.1 nm). Didactical applications of these low cost lasers are discussed.
