Many applications of femtosecond lasers typically require pulse energies that cannot be reliably obtained directly from oscillators. For this reason, the research of efficient and cost-competitive ultrafast amplifiers is still a relevant topic for both scientific and industrial research. In this work, …

In this work, we present a novel amplification module based on a high-brilliance tapered pump laser diode. A monolithic distributed Bragg grating permits to stabilize the diode wavelength, that was kept at 978.5 nm with a full-width at half-maximum bandwidth <0.2 nm …

Monitoring of fish passage at hydropower plants largely relies on stow-fyke-net captures installed downstream of turbine outlets, yet little is known about which fish behavior contributes to reduced catch efficiency. We studied fish-net interactions as well as biological and physical factors potentially …

We report on a newly developed Q-switched diode side-pumped Er:YLF solid state laser emitting at 2.81 μm. Efficient short pulse generation is achieved by utilizing the relatively long lifetime of the upper laser level and the inherently linear polarized laser light of …
