Surface textures with micro-scale feature dimensions still hold great potential to enhance the
frictional performance of tribological systems. Apart from the ability of surface texturing to …

Laser processing with ultra-short double pulses has gained attraction since the beginning of
the 2000s. In the last decade, pulse bursts consisting of multiple pulses with a delay of …

Coherent beam combining of 107 beams has been demonstrated for the first time to the best
of our knowledge. When the system was in closed loop, the pattern in far-field was stable …

We report on the coherent beam combining of 61 femtosecond fiber chirped-pulse amplifiers
in a tiled-aperture configuration along with an interferometric phase measurement …

Ultra-short pulse lasers, generating coherent light pulses with pulse durations in the
picosecond and femtosecond range, are becoming popular in precision laser …

Coherently combining of seven-channel narrow-linewidth, linear-polarized, kW-level power
all-fiber amplifiers has been successfully demonstrated by using the stochastic parallel …

The industrial maturity of ultrashort pulsed lasers has triggered the development of a
plethora of material processing strategies. Recently, the combination of these remarkable …

Ultrafast fiber lasers have gained rapid advances in last decades for their intrinsic merits
such as potential of all-fiber format, excellent beam quality, superior power scalability, and …

The development of high-power diode lasers enabled new solid-state laser concepts such
as thin-disk, fiber, and Innoslab lasers based on trivalent ytterbium as the laser-active ion …

We demonstrate the reliable generation of 1-mJ, 31-fs pulses with an average power of 1 kW
by post-compression of 200-fs pulses from a coherently combined Yb: fiber laser system in …
