A pulsed inductive discharge molecular H2 laser has been created for the first time. The excitation system of a toroidal pulsed inductive discharge for molecular hydrogen electron levels excitation was developed. Generation at two wavelengths of 0,89 and 1,12 µm was obtained. The spectral, temporal and energy parameters of laser emission under various pressures and pumping conditions were investigated. The maximum pulse power of 6,7 kW was achieved. The measured pulse duration was 18 ± 1 ns. In the cross-section, the laser radiation had the ring shape with an external diameter of 33 mm and thickness of 4 mm.
