YactoFiber All-Fiber High-Power Femtosecond Laser YF-FL-20
YactoFiber high-power femtosecond lasers are diode-pumped fiber lasers. All-spliced fiber oscillators and amplifiers avoid power fluctuations associated with free-space coupling, such as rod-fiber limitations, for highly stable average output up to 120W. Dispersion design and nonlinear control enable energies up to 400μJ while retaining short pulses (~250fs). The MOPA architecture provides wide dynamic tuning of pulse width, frequency and power: software adjusts pulse width in real time from 290fs to 10ps, and an internal pulse picker continuously adjusts frequency from single pulses to 1MHz. External functions include pulse-on-demand PoD and Gate control. Industrial optomechanics with no adjustable mirror mounts support reliability and long-term stability. Stored software presets enable one-button activation. Long-life harmonic modules (SHG/THG/FHG) provide 515/343/257nm outputs.
