This paper introduces an all-solid-state lidar system based on optical parametric oscillator (OPO) and optical parametric amplification (OPA) technology, and its application in the detection of atmospheric metal components. The lidar system is distinguished by its high output energy (up to 100 mJ), narrow linewidth (< 200 MHz), and the excellent uniformity of laser spot, which significantly enhances its sensitivity for detecting metal ions in the atmosphere, and a detection sensitivity of 0.02 cm^-3 for metal ions can be achieved at 1 km in 1 hour integration time. In the field experiments conducted in Beijing, Mohe, and other sites, the overnight evolution data of calcium atoms and ions were successfully obtained using the lidar system, and calcium ion layers extending up to 300 km in altitude were detected. These results indicate that, compared with traditional dye laser technology, the all-solid-state lidar has the advantages of high sensitivity and high resolution, and a series of new phenomena detected are expected to promote the discovery of new processes and mechanisms in space physics. In addition, this paper also discusses the prospective applications of this technology in advancing lidar detection capabilities.
