Laser microstructuring has been studied extensively in the last decades due to its versatile, contactless processing and outstanding precision and structure quality on a wide range of materials. A limitation of the approach has been identified in the

Silica fibers have been successful used to deliver high-power high-energy laser beam in the near-infrared and visible range but suffer from high absorption and color formation in the UV spectrum which disqualify then for such wavelength. Recently, th

We report on a single-stage high-power amplification of a radially polarized mode-locked laser beam in a single-crystal fiber (SCF) amplifier. The seed beam was amplified by a factor of 5.0 to an average output power of 66.3 W. The pulse duration of

70 cm long Yb3+-doped Y3Al5O12 (Yb:YAG) single-crystal fibers of 1 and 0.4 mm diameters were grown by the micro-pulling-down method. The structural and optical characterizations of those fibers showed that they exhibited a perfect single crystalline

International audience; Laser emission obtained from an Yb:YAG single-crystal fiber directly grown by the micro-pulling down technique is demonstrated for the first time. We achieved 11.2 W of continuous wave (CW) output power at 1031 nm for 55 W of
