Hello everybody. Good afternoon. greetings from my side!
I think it was a healthy and positive rather productive discussion. All the views put forth by other members are true in one or the other way. So i believe Mr Zulkarnain should have had his confusions cleared regarding high gain efficiency and high power and their co-relation with the non linearities. It would be simply easy to understand if you try to implement it in Optisystem and check out for different results you get. I hope that will help you.
