We report on a novel ytterbium-doped fiber design which combines the advantages of rod and fiber gain media. 120 W output power in single-mode beam quality are obtained from a 48 cm long fiber cane.
We evaluate radio-frequency noise generated during supercontinuum generation in photonic crystal fibers. Dramatically reduced noise is observed when seeding with picosecond pulses compared to ...femtosecond pulses for the same generated bandwidth in the infrared region.
We report on an all fiber CPA system based on a step-index fiber stretcher and an air-guiding photonic crystal fiber compressor. The peak power out of the compressor fiber is as high as 0.82 MW.
We discuss high average power (/spl sim/100 W) and high energy (/spl sim/100 /spl mu/J) femtosecond fiber laser systems and their applications ranging from index modification in transparent materials ...to micromachining of metals.
In this paper, we report on a power scaling of stable cw ytterbium-doped high power fiber laser with 170 W output power based on large-mode-area fibers. Single transverse mode output is obtained from ...a 28 /spl mu/m core diameter low-numerical aperture fiber.
In this paper, we report on realization of an ultrastable single frequency source based on fiber amplification of a nonplanar ring oscillator up to 90 W with diffraction-limited beam quality using ...ytterbium-doped high power fiber laser.
