How does the laser pointer play a role in agriculture?

Laser pointer technology is used to save 25% of water in irrigation and improve the effectiveness of salt leaching, which is a key component of irrigated agricultural soil health. Laser leveling may increase the productivity of fields with uneven slopes, which can lead to ineffective drainage modes. In the laser leveling process, the laser level installed on the tower is combined with the sensor on the wheeled tractor scraper to bring the farmland slightly closer to the flatness for proper drainage. In solid-state lasers, light is generally used as the pump source, and the crystal or glass that can generate laser light is called the laser working material. The laser working substance is composed of two parts: the matrix and the activated ions. The matrix material provides a suitable existence and working environment for the activated ions, and the activated ions complete the laser generation process.
