  We report about an intriguing boiling regime occurring for small heaters
embedded on the boundary in subcooled water. The microheater is realized by
focusing a continuous wave laser beam to about $10\,\mu$m in diameter onto a
165\,nm-thick layer of gold, which is submerged in water. After an initial
vaporous explosion a single bubble oscillates continuously and repeatably at
several $100\,$kHz. The microbubble's oscillations are accompanied with bubble
pinch-off leading to a stream of gaseous bubbles into the subcooled water. The
self-driven bubble oscillation is explained with a thermally kicked oscillator
caused by the non-spherical collapses and by surface pinning. Additionally,
Marangoni stresses induce a recirculating streaming flow which transports cold
liquid towards the microheater reducing diffusion of heat along the substrate
and therefore stabilizing the phenomenon to many million cycles. We speculate
that this oscillate boiling regime may allow to overcome the heat transfer
thresholds observed during the nucleate boiling crisis and offers a new pathway
for heat transfer under microgravity conditions.
