Dear All,

Given wavelength of a laser, how to calculate its free space
propagation constant?

Thanks!

How can you be active in optics without knowing and understanding this most
fundamental aspect of optics? It is k=2*¼/wavelength. But if you do not
understand that, how is knowing it going to be useful? (I hope that the ¼
prints as Greek letter pi.)
