Laser-induced cavitation bubbles in heavy water are investigated at different parameter settings. Neutrons are searched for in close temporal proximity to cavitation luminescence flashes with an estimated detection efficiency of 4%. No neutrons in coincidence with cavitation luminescence have been detected. This yields an upper limit of emitted neutrons per bubble collapse of .
