Can optical power be have some value (cw) even the shutter is close for population inversion after the each pulse! and if the curve is representation of population inversion , would it reach zero (no excited electrons in medium) even shutter is open? and i am a beginner in this topic :D
Thank you Profssor Jena, i'm writing my dissertation on the investigation of ultrafast pulses, so lecture 23-25 are very helpful
Can anyone please let me know which software is using @46:30
Looks like MATLAB to me. You could probably use Wolfram, Python, or really any programming language to get the same result.
Very good, thanks!
Plot in 36:13 is wrong. You plot a multiplication of 2 modes, but e(t)=Sum...!

At 37:52, that is not the sinc function. It should be sin(N * ... * t)/(... * t).
Isn't that sinc function sin theta/theta
sin(Nwt)/(wt) = N*sin(Nwt)/(Nwt) = N*sinc(Nwt)
Still a sinc, just scaled.
