Summary: This work introduces a simple polarization-maintaining wavelength-tunable passive mode-locked Erbium-doped fiber laser with a semiconductor saturable absorber mirror (SESAM) as a mode locker. Tunable mode-locking in the range of 1543.2 nm to 1569.5 nm was achieved by thermally adjusting the FOLM wavelength reflection, resulting in output pulses with a repetition rate of 11.16 MHz and a pulse duration of about 0.9 ps. The experimental results were verified through numerical simulations.

Summary: In this study, we investigate intermodal forward Brillouin scattering in a solid-core photonic crystal fiber, demonstrating efficient power conversion between different modes. By exploring mechanical modes of different symmetries, we observe both polarization-dependent and polarization-independent intermodal Brillouin interaction. Finally, we discuss the role of squeeze film air damping and leakage mechanisms in engineering PCF structures with enhanced interaction between high-order optical modes through flexural mechanical modes.

Summary: Utilizing ultrafast ionization of a gas medium driven by ultrashort midinfrared laser pulses generates a bright ultra-broadband radiation source, with the lowest-frequency part exhibiting significant enhancement at low gas pressures. This behavior is consistent with Cherenkov-type radiation by ponderomotively driven plasma currents.

Summary: The efficiency of nonlinear optical processes in plasma media is limited by the smallness of the velocity of laser-field-induced motion of electrons compared to the speed of light c. Intense ultrashort mid-infrared pulses can significantly enhance weak plasma nonlinearities induced by plasma currents, enabling the efficient generation of coherent broadband terahertz and microwave radiation in laser plasma schemes, known as terahertz-microwave supercontinuum.
