  text: <jats:title>Abstract</jats:title><jats:p>Spin‐controlled lasers are highly
    interesting photonic devices and have been shown to provide ultrafast polarization
    dynamics in excess of 200 GHz. In contrast to conventional semiconductor lasers
    their temporal properties are not limited by the intensity dynamics, but are governed
    primarily by the interaction of the spin dynamics with the birefringent mode splitting
    that determines the polarization oscillation frequency. Another class of modern
    semiconductor lasers are high‐<jats:italic>β</jats:italic> emitters, which benefit
    from enhanced light–matter interaction due to strong mode confinement in low‐mode‐volume
    microcavities. In such structures, the emission properties can be tailored by
    the resonator geometry to realize for instance bimodal emission behavior in slightly
    elliptical micropillar cavities. This attractive feature is utilized to demonstrate
    and explore spin‐lasing effects in bimodal high‐<jats:italic>β</jats:italic> quantum
    dot micropillar lasers. The studied microlasers with a <jats:italic>β</jats:italic>‐factor
    of 4% show spin‐laser effects with experimental polarization oscillation frequencies
    up to 15 GHz and predicted frequencies up to about 100 GHz, which are controlled
    by the ellipticity of the resonator. These results reveal appealing prospects
    for very compact, ultrafast, and energy‐efficient spin‐lasers and can pave the
    way for future purely electrically injected spin‐lasers enabled by short injection
    path lengths.</jats:p>
