Femtosecond Laser-Assisted Keratoplasty

American Journal of Ophthalmology, 2011
T a ( w r B u r HE ACCURACY AND PREDICTABILITY OF FEMTOSECond lasers not only provides new treatment options, but also increases clinical outcomes in refractive rocedures and corneal transplantations. The most imporant advantage of femtosecond laser technology is the bility to create vertical and lamellar corneal incisions ith a limitless variety of ...

High efficiency femtosecond laser ablation with gigahertz level bursts

Journal of laser applications, 2019
The authors report on a simple and easy-to-use GHz amplified femtosecond laser source. The laser source is based on a passively mode-locked oscillator with a near GHz repetition rate.

Yb:CaF2 femtosecond laser

Advanced Solid-State Photonics, 2005
We report the first demonstration of a high power passively mode-locked diode-pumped femtosecond laser based on an Yb3+:CaF2 crystal. Pulses of 150 fs with an average power of 0.88 W and pulse of 230 fs with an average power of 1.74 W have been produced.

Femtosecond Excimer Lasers

SPIE Proceedings, 1989
The bandwidth of most excimer lasers allows the amplification of subpicosecond pulses. In this paper a novel method and experimental arrangement is reported for the generation of femtosecond pulses in the XeF, XeC1 and KrF laser wavelengths. This is based on the use of a hybrid excimer-dye laser arrangement, incorporating a twin tube excimer laser and ...

Ultrabroadband femtosecond lasers

IEEE Journal of Quantum Electronics, 1994
The exploitation of soliton-like pulse shaping mechanisms and the optimization of phase dispersion in broadband self-modelocked solid state laser oscillators have led to unprecedented advances in ultrafast laser technology. This paper reviews the basic physical mechanisms governing pulse formation and addresses the requirements for optimum performance ...

Femtosecond laser machining

Technical Digest. Summaries of Papers Presented at the Conference on Lasers and Electro-Optics. Conference Edition. 1998 Technical Digest Series, Vol.6 (IEEE Cat. No.98CH36178), 1998
Summary form only given. The use of femtosecond lasers allows materials processing of practically any material with extremely high precision and minimal collateral damage. Advantages over conventional laser machining (using pulses longer than a few tens of picoseconds) are realized by depositing the laser energy into the electrons of the material on a ...
