LenSx® Femtosecond Laser System Fundamentals

Touch MEdical MEdia Safe and effective cataract surgery is the goal for both patients and surgeons, with increasing demands for accurate refractive outcomes. Femtosecond laser-assisted cataract surgery (FLACS) is arguably the most significant change to cataract surgery since phacoemulsification, the adoption of which is in large part fueled by the desire for more precise and safe surgery with m...

Femtosecond Laser-Induced Nanowelding: Fundamentals and Applications

Fundamentals of femtosecond laser pulse and nanoparticles are analyzed by a two-temperature model. Ultrafast surface melting, surface nanoengineering and shock wave impact are evident in the surface of graphite by femtosecond irradiation. The interaction between femtosecond laser pulses and Au/Ag nanoparticles has been investigated. Two effects are identified at different intensities: photofrag...

Femtosecond Laser Ablation: Fundamentals and Applications

Traditionally nanosecond laser pulses have been used for Laser-induced Breakdown Spectroscopy (LIBS) for quantitative and qualitative analysis of the samples. Laser produced plasmas using nanosecond laser pulses have been studied extensively since 1960s. With the advent of short and ultrashort laser pulses, there has been a growing interest in the applications of femtosecond and picosecond lase...

Laser microshaping: Fundamentals, practical applications, and future prospects

Today the laser technologies are widely used in the processing of materials, including also the precise microshaping. Deep UV lasers have very good prospects in the lithography, used for fabrication of chips, while the femtosecond pulsed lasers open the new horizons for the microand submicroprofilling. But these are the field of the future prospects. As for today state-of-the-art, contribution ...
