Abstract
In this work, the time-scale laser-induced voltage (LIV) of air was investigated under KrF excimer laser irradiation. The LIV response was fitted by a sum of three exponential functions, where the fitted parameters were influenced by the bias voltage Vb and the laser energy Ein. Higher Vb produced significant LIV. An exponential relationship was observed between the Ein and LIV signal amplitude (Vp). After decreasing the adjustable resistor, the LIV trace was almost triangular and symmetrical due to the impedance effect with the response time which was completely limited by the laser pulse duration. As a potential application, the LIV of air presented a viable method for single-pulse laser detection.
