A high‐power wavelength‐tunable femtosecond fiber laser source is developed based on photonic‐crystal fiber technology. Laser oscillator and amplifier stages in this system employ diode‐pumped ytterbium‐doped single‐polarization large‐modearea photonic‐crystal fibers in a stretcher‐free configuratio...
