Which is equal to imagianry part of the wavector inside the gain medium.
Mauro Andrea Bettiati,
I'm interested not in the modal gain, which depends on geometry of the structure. I would like to know what the gain mateiral itself is capable of whatever the geometry of the system is.
few thousands 1/cm - the same value (on the order of magnitude) as for organic dyes?
Without using commercial kits.
