300-mW average power in 22-fs pulses from a multi-mode diode pumped Yb:CALGO oscillator [PDF]

open access: yesEPJ Web of Conferences
We present a multi-mode diode-pumped Yb:CALGO laser oscillator based on cross-polarization pumping. Using this method, we demonstrate 22-fs pulses at 0.3 W, which is the shortest duration for any Yb- based bulk laser oscillator utilizing multimode-diode ...

Ultralow-noise photonic microwave synthesis using a soliton microcomb-based transfer oscillator

open access: yesNature Communications, 2020
In order to satisfy a wide range of modern microwave applications, improved methods are needed to produce low-noise microwave signals. Here the authors demonstrate ultra-low noise microwave synthesis via optical frequency division using a transfer ...

The Impact of Emotion on Musical Long-Term Memory

open access: yesFrontiers in Psychology, 2020
The influence of emotional dimensions such as arousal and valence on memory has been a topic of particularly intense inquiry. As stimuli go, music is capable of provoking strong emotional responses from listeners, which can in turn influence memory ...

The Contribution of Basic Psychological Need Satisfaction to Psychological Well-Being via Autonomous Motivation Among Older Adults: A Cross-Cultural Study in China and France

open access: yesFrontiers in Psychology, 2021
According to self-determination theory (SDT), the satisfaction of the universal needs for autonomy, competence, and relatedness is important in order to enhance autonomous motivation, which in turn promotes psychological well-being (PWB), regardless of ...

Carrier-Envelope Offset Frequency Stabilization of a Fiber Laser by Cross Gain Modulation

open access: yesIEEE Photonics Journal, 2018
We present the first carrier-envelope offset (CEO) frequency stabilization of a fiber laser by cross gain modulation. The Yb-doped fiber laser is mode-locked by nonlinear polarization evolution and emits 32-nm wide dissipative solitons at a repetition ...
