Longitudinal mode-coupling instabilities of proton bunches in the CERN Super Proton Synchrotron
Physical Review Accelerators and Beams, 2023 In this paper, we study single-bunch instabilities observed in the CERN Super Proton Synchrotron (SPS). According to the linearized Vlasov theory, radial or azimuthal mode-coupling instabilities result from a coupling of bunch-oscillation modes, which ...

Impact of Mode Switching on Nonresponse and Bias in a Multimode Longitudinal Study of Young Adults
Survey Research Methods, 2023 Young adults are generally hard to survey, presenting researchers with numerous difficulties. They are hard to locate and contact due to high mobility. They are hard to persuade and exhibit high levels of resistance to survey participation. As a result,

Compound four-cavity single-longitudinal mode fiber laser
Optics ExpressA compound resonant cavity-type single longitudinal mode erbium-doped fiber laser is proposed and verified in this paper. We use a compound four-cavity to expand the longitudinal mode spacing of the laser and a homemade grating F-P filter and a saturable absorber to narrow the gain spectral bandwidth, enabling the laser to operate in a single-frequency

Single-longitudinal-mode tunable WDM-channel-selectable fiber laser
Optics Express, 2002 We report operation of a single-longitudinal-mode WDMchannel-selectable fiber laser. The use of a tunable fiber Bragg grating and a linewidth narrowing saturable absorption filter in conjunction with an intracavity etalon enabled single-frequency emission and discretely tunable WDM channel operation without the need for external wavelength locking ...

Single-longitudinal-mode vortex Nd:YVO4 laser using a circular Dammann grating for pump shaping
Applied Physics ExpressIn this research, a 1064 nm single-longitudinal-mode (SLM) vortex beam was generated from an annular-pumped Nd:YVO _4 microchip laser, in which a circular Dammann grating was used to reshape the 808 nm pump light into an annular intensity profile.
