SEGA mode locking, first experimental indications of operation

Research output: Contribution to conferencePoster

Abstract

We present an alternative scheme for laser mode-locking and discuss its first experimental indications of operation. In this scheme, a large set of spatially separated gain (SEGA) media generate single-frequency continuous-wave (CW) light beams arranged as an approximately equidistant spectral frequency comb. After combining the beams, a common saturable absorber causes mutual phase locking. As a result, a fully equidistant frequency comb, and ultra short pulses with extremely high repetition rates and high average output power are expected. The set of frequencies on which the laser oscillates, and therefore the pulse repetition rate, can be controlled by resonator-internal optical elements, rather than cavity length. We examined spectral and time-resolved intensity autocorrelation properties of the SEGA laser. We observed an improved equidistance in the frequency comb and peaks in the autocorrelation. By exchanging one of the optical elements but keeping the laser cavity size equal, we observe a corresponding change of the repetition rates from 21 GHz to 69 GHz.
