Ok, seriously ..... W are power, J are power in time, so, 1J = 1W/Second.
But for the cavity, you're usually indicating the power for the duration of the pulse (this i meant with "depend" ), so, if the pulse is the usual 100 microseconds, that is the pulse lenght that is normally used with the SSY1 assemblies, it means 1W/100 microseconds, that if you convert it in W/S, give you 10 KW (this, ofcourse, if the pulse was 1 second long ..... and, basically also mean that the power at the hitting point is equivalent to 10 Kw, but ofcourse, being long only 100 microseconds, the transferred energy is 1W)
Anyway, i doubt that a SSY1 assembly can last enough time at 1J output, cause that unit was designed for work around 50 milliJoule max ..... maybe it can last 20 or 30 shots, before the q-switch die.
A different thing is, if like me, Anselmo removed the q-switch ..... in this case, the pulses are no more regulated in lenght, and can also get 1 millisecond pulse, with 1 J of output energy, pumping the lamp with 25 or 30 J for a millisecond ..... but still this shorten the life of the assembly, especially the lamp and rod faces .....
