RING LASER WITH THERMALLY STABLE INTRACAVITY FREQUENCY-COMB GENERATION

원문 (중국어)

A ring laser includes an optical amplifier, a birefringent resonator, a polarizing beamsplitter, and a bandpass filter forming a ring cavity. The resonator has a first series of resonances corresponding to a first linear polarization and a second series of resonances corresponding to a second linear polarization orthogonal to the first linear polarization. The ring laser generates intracavity pump light having the first linear polarization. The resonator generates stimulated Brillouin laser (SBL) light in response to the pump light coupling to a first resonance of the first series of resonances, the SBL light having the second linear polarization. The resonator generates dissipative Kerr solitons in response to the SBL light coupling to a second resonance of the second series of resonances, the dissipative Kerr solitons having the second linear polarization. The solitons form a frequency comb that is coupled out of the ring cavity via the polarizing beamsplitter.
