DOI: 10.1007/s11801-017-7009-6

Abstract: In this paper, a self-mode-locked Nd:YVO4 picosecond vortex laser is demonstrated, which can operate on the different Laguerre-Gaussian (LG) modes at 1 064 nm. A π/2 mode converter is utilized to realize the picosecond vortex… read more here.

DOI: 10.1109/jlt.2025.3527702

Abstract: In this paper, a self-mode-locking optoelectronic oscillator (SML-OEO) is proposed and experimentally analyzed for self-excited microwave pulse generation. The SML-OEO shows the ability to realize phase coherence of the oscillating modes in the OEO cavity,… read more here.

DOI: 10.1364/ao.56.009079

Abstract: Sustained self-pulsing and self-mode-locking (SML) are detrimental to the performance of continuous-wave (CW) fiber lasers. We demonstrate an all-fiber method to eliminate SML pulsing by employing a low-reflectivity fiber Bragg grating (FBG) outside of a… read more here.

DOI: 10.1364/ao.56.009552

Abstract: We demonstrate efficient self-mode-locked green and red lasers with repetition rates of tens and hundreds of megahertz in a Pr:YLF crystal. Using double-end blue-diode-pumped geometry, more than 0.68 W average output power at 522 nm and more… read more here.

DOI: 10.1364/oe.572206

Abstract: The mode-locking characteristic and microwave pulses regulation based on a self-mode-locking optoelectronic oscillator (SML-OEO) are analyzed and experimentally demonstrated. The oscillating modes in the SML-OEO cavity can be phase-coherent by means of the inherent oscillatory… read more here.

DOI: 10.3389/fpsyg.2024.1441953

Abstract: Introduction This research identifies and explores two distinct modes of self-experience and their influence on psychological openness. We distinguish between the unitary self-mode, where individuals perceive themselves as cohesive, stable entities, and the multiple self-mode,… read more here.
