Abstract We develop an ultrafast Yb-fiber laser system based on eight-channel coherent beam combining utilizing commercially available rod-type Yb-fibers. To ensure good combining efficiency and long-term operation of the system at the attosecond laser facility under construction, we fully stabilize the phase, group-delay, and beam-pointing of the eight fiber channels. Especially, we propose a novel multi-step hill climbing method to control both group-delay and beam-pointing. At a repetition rate of 1 MHz, this laser system delivers 270-fs pulses with 1.18-kW average power (1.18-mJ pulse energy). The average-power instability of the laser system running for 12 hours is 0.32 %.

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.
