Abstract

The study of pattern formation in the transverse section of lasers with plane cavity mirrors shows that the fundamental solutions are transverse traveling waves. On the other hand, lasers with curved cavity mirrors generate outputs which look like a combination of empty cavity modes. The mechanism behind the selection of travelling waves and cavity modes was found to be analogous. Numerical simulations show that for large input energy (pump), patterns of travelling wave nature are recovered even the mirrors are curved. As the radius of curved mirrors decreases the threshold value of the pump increase.
