Meteoric atoms and ions are among the remarkable tracers to investigate a variety of dynamics appearing in the mesosphere and thermosphere at altitudes ranging from 80 to 150 km. Here, we report on a solid-laser-based lidar system, namely dual-wavelength injection-locked nanosecond-pulsed Ti:sapphire lidar, that can simultaneously detect resonance scatterings by meteoric calcium atom (Ca) and ion (Ca+) layers. We operated the lidar system and conducted a benchmark test in which Ca or Ca+ was observed independently as a first step. We found that the lidar system was operated stably over an entire night, having the ability to detect either Ca or Ca+ with a sufficient signal-to-noise ratio in addition to high temporal and spatial resolutions. In our presentation, we also report on a typical demonstration of the lidar system, namely the observation of Ca and Ca+ over an entire night.
