Visible femtosecond fiber laser
Optics Letters, 2023Femtosecond fiber lasers have revolutionized the industry of laser technology by providing ultrashort pulses of high brightness through compact, affordable, and reliable setups. In this work, we extend the scope of application of such sources by reporting, to our knowledge, the first femtosecond fiber laser operating in the visible spectrum.

The benefits and drawbacks of femtosecond laser-assisted cataract surgery
European Journal of Ophthalmology, 2020Introduction: Since the introduction, femtosecond laser-assisted cataract surgery was believed to revolutionize cataract surgery. However, the judgment of clinical benefit was found to be far more complex than initially might have been thought.

Corneal Trephination With the Femtosecond Laser
Cornea, 2006To evaluate the feasibility and cut quality of corneal trephination in human donor corneal tissue with the femtosecond laser.Twelve human corneoscleral discs were inserted in an artificial anterior chamber. After corneal thickness measurement and tonometry, the cornea was mounted on a femtosecond laser (FEMTEC; 20/10 Perfect Vision, Heidelberg, Germany)

Micro/nano-structures-enhanced triboelectric nanogenerators by femtosecond laser direct writing
Nano Energy, 2019Triboelectric nanogenerator (TENG) is a new energy technology based on interface contact electrification, in which the surface micro/nano-structures of triboelectric layers have great impacts on output performances. Here, we propose micro/nano-structures-

Ultrafast Phenomena, 1994
Recent advances in mode-locked solid-state lasers have resulted in pulses as short as 8.5 fs in the 800 nm region from Ti:sapphire oscillators [1]. Using similar techniques, sub-50 fs pulses [2-4] have been generated in another solid-state laser system, Cr:forsterite, which operates in the 1.2 to 1.3 μm range.

An Investigation of Femtosecond Laser Micromachining
2005 International Conference on MEMS,NANO and Smart Systems, 2006Femtosecond laser micromachining is a new approach emerging in MEMS area in recent years. Although some applications have been reported, this technology is still not matured and not understood very well. Femtosecond lasers currently show much promise as potential effective tools in micromachining or micro-system applications, which include industrial ...

Vortices in femtosecond laser fields
Optics Letters, 2004We experimentally generate optical vortices in the output beam of a 20-fs Ti:sapphire laser. Screw phase dislocations are imposed on the spectral components of the short pulses by aligning a computer-generated hologram in a dispersionless 4f setup.
