We propose and experimentally demonstrate a scheme of achieving high-energy low-temporal-coherence instantaneous broadband light pulses. The low-temporal-coherence instantaneous broadband pulse with a large bandwidth (10.2 nm) and high energy (35 J) in the high gain (more than 10^7 times) laser system was safely created. The coherence time of the output pulse is 318 fs with a 3 ns pulse duration. The excellent near-field beam quality and focusability of the pulse can be comparable to that of conventional coherent lasers. To the best of our knowledge, this is the highest energy of a low-temporal-coherence instantaneous broad-bandwidth pulse reported thus far.
