The segmentation or the geometric analysis of specular objects is known as a difficult problem in the computer vision domain. It is also true for the problem of line detection where the specular reflection implies numerous false positive line detecti

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

The progresses in the micropulling-down technique allow heavy scintillating crystals to be grown directly into a fibre geometry of variable shape, length and diameter. Examples of materials that can be grown with this technique are Lutetium Aluminum

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
