Greetings,
I am an electronic engineer doing some research on high power laser diodes.
The problem I try to solve needs ~2300W of optical peak power coming from a high power laser diode.
The pulses must be with very long (30ms) at very low repetition rates (2Hz).
So,the duty cycle is DC = 0.06.
The calculations I do with the above parameters yield an average power
Pav= Ppeak x DC = 2300 x 0.06 = 138W.
Now the confusing part:
I have been told that the "average optical power" is not equal with the "optical power in CW mode" for very long pulses and very low repetition rates.
Hence, I can not use a laser diode which has 140W optical power in CW mode to get the needed ~2300W peak power.
Is that true ? Why ?
Are there any formulas that I can use to do the calculations for very long pulses to drive a laser diode ?
Any suggested books to read would be greate help..
Best Regards
chris
