Invited talk

Degenerate optical parametric oscillators (DOPOs) based on Kerr nonlinear microresonators have emerged as a promising platform for applications ranging from squeezed-light generation to photonic computing [1–3]. While significant progress has been made in understanding their steady-state operation, their nonlinear dynamical behaviour remains comparatively unexplored.

Here, we theoretically...

Power scaling of fibre lasers and amplifiers whilst maintaining excellent beam quality is important for defence, micro-machining, wind lidar, and scientific discoveries. Single spatial fibre mode systems are reaching limits of power-scaling due to limitations imposed by thermal and non-linear effects; the dominant effect for narrow linewidth light being stimulated Brillouin scattering....

Fibre-based frequency references offer a robust and cost-effective alternative to cavity-stabilised lasers for precision interferometry, including for space-based laser interferometer links. However, the long fibre coils used in these systems are highly sensitive to temperature fluctuations, necessitating effective thermal isolation. We have designed a multi-layer in-vacuum thermal shield to...

475. The Shortest Optical Pulses in the Complex Short Pulse Equation

Contributed Oral

The propagation of optical pulses approaching the single-cycle limit requires mathematical models that extend beyond the slowly varying envelope approximation. While the Short Pulse Equation (SPE) provides an integrable model for the real-valued electric field of ultra-short pulses, the Complex Short Pulse Equation (CSPE) generalizes this framework to the analytic signal associated with the...
