Impact of resonant dispersion on the sensitivity of intracavity phase interferometry and laser gyros
Optics Express, 2016 Intracavity phase interferometry is a phase sensing technique using mode-locked lasers in which two intracavity pulses circulate. The beat frequency between the two output frequency combs is proportional to a phase shift to be measured. A laser gyro is a particular implementation of this device.

Natural Crystal Structure for Generating Raman-Like Orbital Angular Momentum States. [PDF]
Adv Sci (Weinh)This work proposes a strategy for symmetry breaking of the degenerate OAM states relying on the natural anisotropy of crystal gain, to select the handedness of the spatial spiral phase front and further tunable Raman‐like OAM states by thermal‐driven, which clarifies the contribution of intrinsic crystal property to the OAM states and opens a new route

New opportunities for creating quantum states of light and matter with intense laser fields. [PDF]
NanophotonicsAbstract Nonlinear dynamics provide an indispensable resource for creating quantum states of light, as well as other bosonic systems. Seminal work using second‐ and third‐order nonlinear optical crystals, cavity quantum electrodynamics, and superconducting circuits, have enabled generating squeezed states, as well as various non‐Gaussian quantum states

Advanced Photonics Research, Volume 4, Issue 9, September 2023., 2023 Noise‐like pulses (NLPs) are becoming increasingly attractive, whereas few studies have been reported in the mid‐infrared. By exploiting a polarization‐maintaining (PM) fluoride fiber to cause a polarization‐dependent delay between the orthogonal‐polarized components of intracavity circulating pulses, this work theoretically and experimentally ...
