Abstract A diode dual-end-pumped Nd:YVO4 regenerative amplifier was reported. The influence of the cavity stability on the performance of the regenerative amplifier was studied. The experimental results matched well with the analysis at high pump power. The mode locking seed pulses with 15 ps pulse width and 10 nJ single pulse energy at 86 MHz were amplified up to 4.7 mJ at 1 kHz, corresponding to the maximum amplification about 0.5×106, by our regenerative amplifier. And an average power of 4.7 W was obtained at the repetition rate from 1 kHz to 10 kHz.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
