Femtosecond Semiconductor Lasers
CLEO:2011 - Laser Applications to Photonic Applications, 2011Passive modelocking of surface-emitting semiconductor quantum well lasers can generate transform-limited optical pulses with duration comparable to the carrier-carrier scattering time. The presentation describes recent advances in this field.

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)

Nitrogen-vacancy defects in diamond produced by femtosecond laser nanoablation technique
, 2017A strategy for nitrogen-vacancy (NV) center production in diamond under its irradiation by 266-nm femtosecond laser pulses is suggested: NV centers can be effectively and controllably created in the regime of nanoablation of a diamond surface.

Microfabrication by femtosecond laser irradiation
SPIE Proceedings, 2000Femtosecond (fs) laser microfabrication has been gathering more research interests due to its ability to create micro- and sub-micrometer three-dimensional (3D) structures. An extremely high light intensity (—TW/cm2) enables multiphoton absorption (MPA) in transparent materials, upon which the spatial resolution of fabricated elements is confined to ...

Advances in ultrashort-pulse laser technology have led to few-cycle-duration optical pulses, with octave-spanning spectra, generated directly from laser oscillators at high repetition rates. These new laser systems promise to be reliable sources of carrier-envelope-phase-stabilized femtosecond pulse trains and highly stable laser frequency combs.

Femtosecond lasers with a repetition rate of approximately 1 GHz are commonly used frequency comb generators for precise optical frequency metrology. They are conveniently compact, yield unambiguous frequency readings with the help of a commercial wavemeter, and can yield greater heterodyne beat signals against a cw laser than systems with lower ...
