Comparison of nonresonant pumping schemes in ray simulations for (a) a circular cavity and (b) a quadrupole-deformed microcavity.
(a) Ray model for the calculation of the intracavity pump intensity when pumped by a plane wave. (b) Average density of ray as function of the angle of incidence for (i) quadrupolar and (ii) circular microcavities.
Cavity-modified fluorescence and lasing spectra of our QDM, observed for pump power of 22, 33, and , respectively.
(a) Observed lasing threshold curve for a pumping angle of 50° for our QDM. (b) Inverse of the threshold pump power vs the pumping angle, normalized with respect to (i) for our QDM and (ii) for an undeformed circular cavity with the same as our QDM.
(Color) Calculated wave distributions for our QDM when a plane wave satisfying is incident at various pumping angles: (a) 90°, (b) 60°, (c) 45°, (d) 30°, and (e) 0°. The pump wavelength is in nonresonant condition. A scar mode of with is shown in (k). In (f)–(j), intensity-intensity overlap with the scar mode is shown just below each wave distribution. (l) Overlap integral as a function of the pumping angle, normalized with respect to .
