Abstract
We demonstrate a compact high-power ultraviolet multiwavelength femtosecond laser source, where both an oscillator and an amplifier are based on a diode-pumped ytterbium-doped single-polarization large-mode-area photonic-crystal fiber and multiple wavelengths are generated through cascaded frequency mixing in nonlinear crystals. Tunable ultraviolet pulses within the wavelength range from 257 to 263 nm have been produced with maximum average powers of 2.14 and 0.81 W for pulse widths of 410 and 120 fs, respectively, through fourth-harmonic generation in different lengths of β-barium borate crystal.
