We present a CO2-laser based machining process for the manufacturing of all-fiber components. A CO2-laser beam is used to perform multiple steps of the manufacturing chain. The first step is the removal of the fiber’s polymer coating, followed by t

We report gamma radiation influence on an active Er3+ doped fiber amplifier. Hydrogenation of active fibers under special condition allowed for a radiation hardness increase by an order of magnitude. Stability and longevity of hydrogenation effects a

We report the first fully monolithic, polarized, fiber amplifier based on resonantly pumped Holmium doped optical fibers at wavelength longer than 2050 nm. With commercially available fibers, it was possible to achieve Watt level output powers at 208

On-sky tests conducted with an astro-comb using the Potsdam Multi-Aperture Spectrograph (PMAS) at the 3.5 m Calar Alto Telescope are reported. The proposed astro-comb approach is based on cascaded four-wave mixing between two lasers propagating throu

We present a turn-key pulsed polarized Holmium doped fiber source at 2088 nm. In our experimental setup we are utilizing an acousto-optic modulator as a mode-locker or Q-switch. The linear cavity is comprised of a fiber Bragg grating (FBG) pair with
