Abstract

We observed resonance effects on the transmission of a pump beam in a chaotic microcavity in an optimal free-space optical-pumping configuration. The far-field pattern of cavity transmission was significantly modified when the pump laser was resonant with a scar mode. From the difference between the non-resonant and on-resonance transmission patterns, we obtained the efficiency of the pump coupling into the scar mode to be as high as 45%, which is consistent with the recent excitation spectroscopy results of Yang et al. [Phys. Rev. Lett. 104, 243601 (2010)].

摘要

我们在最优自由空间光泵浦配置下，观察到了混沌微腔中泵浦光束传输的共振效应。当泵浦激光与一种疤痕模式共振时，腔传输的远场模式会显著改变。通过非共振和共振传输模式之间的差异，我们得到泵浦耦合到疤痕模式的效率高达45%，这与Yang等人最近的激发光谱结果[《物理评论快报》104, 243601 (2010)]一致。
