The solar water pump is a system that uses electrical energy from the sun's light source. This technology has begun to be developed and applied to various aspects, one of which is the agricultural and plantation irrigation system in the concept of smart farming. The application of SWPS, which is user-friendly, easy to monitor and control, easy and inexpensive to maintain, and provides many benefits, makes this technology widely applied in the agricultural and plantation sectors, one of which is Thailand. This study aims to determine the application and usefulness of SWPS in agricultural and plantation irrigation, which is integrated into the smart farming concept. The method used in this research is descriptive qualitative. Collecting data is done through direct observation of SWPS users, while the analysis is carried out descriptively. Thailand uses SWPS in agricultural and plantation irrigation systems to support food security as part of implementing smart farming. SWPS has proven to be effective and efficient in providing water for irrigation. This technology is easy to operate and maintain and is inexpensive to maintain. The application of SWPS is also very much cheaper when compared to the use of diesel to drive pumps in agriculture or plantations, where the need is relatively high. Applying SWPS irrigation systems benefits farmers in terms of increasing the productivity of agricultural products, increasing income, increasing the efficiency of agricultural processes, and improving product quality.

The underdevelopment of mid‐infrared (MIR) components and detectors greatly limits the spatial resolution and sensitivity of MIR imaging. To overcome these limitations, MIR detail‐enhanced imaging is enhanced via non‐degenerate optical parametric amplification (OPA) pumped by a femtosecond vortex pulse. This design renders MIR illumination into a visible image by nonlinear wavelength‐conversion, together with a high OPA gain, large spatial bandwidth, and remarkable sensitivity. These experiments show that the design can realize MIR imaging with a spatial resolution of up to 114 line pairs per millimeter and a 2D spatial bandwidth product of up to 62 900, over a spectral region tunable from 2.0 to 3.0 µm. Equally important, this setup simultaneously achieves excellent imaging sensitivity of 25 photons at room temperature. It is thought that this work provides a powerful way to realize effective real‐time MIR imaging with an excellent spatial resolution even in very weak illumination environments, which can benefit many applications from semiconductor material characterization and biomedical imaging to security.
