A tunable negative coefficient band-pass microwave photonic filter (MPF) with improved mainlobe-to-sidelobe suppression ratio (MSSR) by a Sagnac interferometer (SI) is experimentally demonstrated. The negative coefficient characteristic of MPF is achieved
The interaction of ultra-intense high-power lasers with solid-state targets has been largely studied for the past 20 years as a future compact proton and ion source. Indeed, the huge potential established on the target surface by the escaping electrons pr
By adopting a distributed feedback laser (DFBL) centered at 1.654 μm, a near-infrared (NIR) methane (CH4) detection system based on tunable diode laser absorption spectroscopy (TDLAS) is experimentally demonstrated. A laser temperature control
Two models to calculate the irradiance threshold for laser-induced breakdown for water have been introduced. Both of the models have been incorporated into a computer code and code results compared to experimentally measured irradiance threshold for break
