pulse energy 

of a laser
https://doi.org/10.1351/goldbook.08531
Total optical energy content of a laser pulse. Integral of optical power over pulse duration.
Note:
Pulse energies range from microjoules to millijoules for Q-switched lasers, whereas mode-locked lasers achieve much lower pulse energies (picojoules, nanojoules or sometimes several microjoules).
