We have studied on operational characteristics of the nitrogen laser with sliding discharge and longitudinal excitation. We could observe radiation of nitrogen laser excited by a sliding discharge along the surface of a dielectric. The shape of the beam was a ring type which had 2 mm or 4mm in diameter depending on the sliding discharge tube shape. In this experiment, We show the possibilities to make other shapes of laser beam, for example, rectangle, ellipse, and to excite another gas laser system like an excimer laser.
