Time-resolved spectroscopy of noise-driven collective states of light
Diego Piciocchi, Ina Heckelmann, Alexander Dikopoltsev +6
We study a collective liquid state of light in a fast-gain laser. Controlled temporal noise on the cavity modulation creates a fluctuating linear potential along the synthetic freq…
