I feel like a moron for not knowing the answer to this.
I'm looking for a laser that can deliver a single 3mJ, 10nS pulse. Most of the laser specs I've found report the laser power in watts rather than the energy in mJ. So I did the following calculation:
3mJ/10nS=3x105J/S=300kW
But there is no possible way I need a 300kW laser! The lasers that typically deliver these sort of 3mJ, 10nS pulses are rated as 10W, 30W, or maybe 200W. Definitely not over 1000W! So where has my calculation gone astray?
