Well, schrecken's little box has a power of 3kW during the on time, which is very short , and then has to charge for 30 seconds for another shot. :P

Thanks everybody for the opinions! It seems like there is no real advantage for burning/ pointing/ beam appeal for pulsed lasers since they are rated for the Average power. It seems like there is 3 restrictions to the laser diode good operation: Static electricity discharge, Temperature of the diode and current/voltage applied. Speaking of current/voltage i have noticed that the diode´s life is inversely proportional to the current applied, and that relationship obeys a powertype function( correct me if i´m wrong), where life of diode is equal to a constant times (the current powered by a constant exponent), and the COD current(or smaller than 10seconds life) is about 3X or 4X times the CW rated current. So if i would calculate the average life of the pulsed diode it would give me a smaller number(excluding the temperature and eletrical discharge limits) than the CW, if for example i raise the peak power of a pulsed diode by X2 of CW and limit the duty cycle for 50%, this would give the same average power of the CW, but a smaller life since for double of the power used at the peak, the life would diminish by MORE than a half from the CW( assuming that doubling the power doubles the current applied) Please correct me if i´m wrong at some point of this idea.
