Interactions were characterized for the first time between pea cultivars and the fungus Aphanomyces euteiches at Finnish trial sites on soils with and without common root rot caused by the fungus. Seed yield, protein content, growing time, duration o

We present a modelocked femtosecond thin disk laser that generates pulse energies beyond the 10-μJ limit. We discuss the first photoelectron imaging spectroscopy measurements at multi-megahertz repetition rate, which is advantageous due to high sign

We report on a passively mode-locked Yb:YAG thin disk laser oscillator that generates 11.3-microJ pulses without the use of any additional external amplification. A repetition rate of 4 MHz is obtained using a 23.4-m-long multiple-pass cavity that ex

We present a SESAM-modelocked Yb:YAG laser generating nearly transform-limited femtosecond pulses with 11-muJ energy at 4 MHz repetition rate and excellent beam quality. We discuss the key challenges for further increase of the pulse energy.

The first passively mode-locked Yb:Lu2O3 thin disk laser generates 370-fs pulses with 20.5 W average power. Yb:Lu2O3 is an excellent alternative to femtosecond Yb:YAG thin disk lasers, achieving higher optical-to-optical efficiencies and shorter puls

We demonstrate the first mode-locked Yb:Lu2O3thin disk laser, obtaining 370-fs pulses with 20.5 W average power. The 43% optical-to-optical efficiency obtained with 523-fs pulses is higher than for previous mode-locked thin disk lasers.

We demonstrate the first passively mode-locked thin disk laser based on Yb:Lu(2)O(3). The laser generates 370-fs pulses with 20.5 W of average power in a diffraction-limited beam (M(2)1.1). The nearly transform-limited pulses have a spectral bandwidt
