The limit of detection of lead in LIBS of the heated soil target has been determined as 3.8 ppm. This study reveals the potential application of the LIBS of a pre-heated target for the detection of lead with an improved LOD in the environmental sample.Space-based gravitational wave detection programs, like the Laser Interferometer Space Antenna or the Taiji program, aim to detect gravitational waves in space with interferometric arms of millions of kilometers. In the process of far-field propagation, the exit wavefront error of the trans
