The stationary lasing of the modes in a microdisk is formulated as a nonlinear eigenvalue problem for a nonlinear Maxwell equation. It is shown that whispering gallery modes can be obtained as stationary lasing solutions with finite pumping thresholds. Further, it is discovered that whispering gallery lasing modes can exist even though the angle of incidence to the disk boundary is smaller than the critical angle for total internal reflection.
