Abstract

Data from GaN micro-disk lasers at various deformations, where the lasing modes are found to be based on distinct perioidic ray orbits (PROs), but with varying stabilites is reported. The quadrupolar-deformed laser (QD) at ε=0.12 analyzed in detail is found to lase on unstable triangular PROs, which strike the boundary near the critical angle. In case of the hexa-decapolar deformed laser (Q-HD), it is shown that one and the same PRO is responsible for lasing over a wide range of deformations, although it undergoes a stable-to-unstable transition in that range.
