Enhanced nonresonant optical pumping based on turnstile transport in a chaotic microcavity laser

We report efficient nonresonant optical pumping based on turnstile transport in a chaotic microcavity laser. We observed more than tenfold enhancement in the pumping efficiency at a particular pumping angle and at a particular boundary position of the microcavity while these angle and position are c...

Description
Summary:We report efficient nonresonant optical pumping based on turnstile transport in a chaotic microcavity laser. We observed more than tenfold enhancement in the pumping efficiency at a particular pumping angle and at a particular boundary position of the microcavity while these angle and position are consistent with the turnstile transport mechanism in chaotic ray dynamics. The pumping efficiency distribution resembles that of the output emission for the same cavity, supporting the concept of time-reversed ray transport.
