High-average-power picosecond Yb-doped fiber amplifier

Abstract

We report on a cladding-pumped, ytterbium-doped large-core-area fiber amplifier that is capable of generating 51.2 W of average power at a 1064-nm center wavelength, an 80-MHz repetition rate, and a 10-ps pulse duration. In an ytterbium-doped large-mode-area fiber these pulses could be amplified up to 43.2 W with diffraction-limited beam quality (M(2)~1.3) . Power scaling limitations that arise from nonlinear distortions such as self-phase modulation and stimulated Raman scattering are discussed.

Effect of ultrashort pulsed laser on bond strength of Y-TZP zirconia ceramic to tooth surfaces

“…Featuring high lasing efficiency and broadband tunability, ytterbium-pulsed lasers with high peak power operating in Q-switched and mode-locking regimes are a rapidly advancing area of ultrashort laser applications [25][26][27] . With radiation around the wavelength range of 1,030-1,080 nm, Q-switched ytterbium fiber lasers are becoming an attractive alternative to Nd:YAG lasers-which employs a wavelength of 1,064 nm and which traditionally occupies a large sector of the medical applications industry.…”

100W, single mode, single polarization, picosecond, ytterbium doped fibre MOPA frequency doubled to 530 nm

“…Herein we present a fiberised, diode-seeded, YDFA MOPA system generating linearly polarized, diffraction-limited, 20ps pulses at repetition rates ranging from 113.5 MHz to 908 MHz and at average output powers in excess of 100W. This system represents a considerable improvement in practicality and performance relative to previous high power, fiber-based ps pulse sources [3]. The output of the MOPA was launched into an LBO crystal to generate 45W of green light.…”
