We report on a widely tunable ytterbium fs-fiber laser without dispersion compensation. The all-normal dispersion laser contains a spectral filter for wavelength tuning and for generating additional amplitude modulation to support the nonlinear polar

This paper addresses recent developments in ultrafast fiber oscillators achieved by the operation in the normal dispersion regime. Based on experimental and numerical results, key features of the pulse formation and stability in the resonator will be

We report on a widely tunable, pulsed laser system with narrow spectral linewidth based on a continuous wave ytterbium fiber oscillator, a pulse shaper and a power amplifier stage. The system is tunable from 1055 nm to 1085 nm and provides a maximum

We report on direct writing of three-dimensional structures within the bulk of the Er3+-doped oxyfluoride precursor glass using tightly focused femtosecond Ti-sapphire laser pulses at 800 nm wavelength. Buried 1 µm diameter channel and spherical wav

We report on a diode-pumped double-slab Yb:KYW regenerative amplifier with combined gain spectra and intracavity dispersion compensation. At repetition rates > 20 kHz an average power of up to 5 W after compression was generated, resulting in a maxim

Passively mode-locked ultrafast ytterbium fiber lasers operating in the wavelength range around 1 µm are subject of intensive investigations during the past years owing to their great potential of realizing cost-effective and compact set-ups [1]. Pa

We report on an high power ultra-short pulse regenerative Yb:KLuW amplifier based on the thin disk concept. A maximum pulse energy of 571 microJ was extracted at a repetition rate of 20 kHz. Compression of the output pulses resulted in a pulse durati

We present a sub-85 fs self-starting stretched-pulse passively mode-locked Erbium-fiber oscillator in a sigma setup with tunable repetition rate. The sigma cavity included a movable mirror enabling a tunable pulse repetition rate variation of +/- 1 %

In order to profit from all the benefits of a waveguide laser device like alignment-free and maintenance-free operation, decoupling from technical noise, and compactness an all fiber setup is highly desirable. Recently, all-fiber lasers utilizing a s
