We describe a technique that uses a neodymium:YAG (Nd:YAG) laser photolysis system to prevent lens capsule opacification. The photolysis instrument consists of a 1064 nm Nd:YAG laser transmitted along a fiber-optic cable into a handpiece containing a

Dynamic parameters such as the extension of the ablation cloud, the initial velocity and momentum of the ablated particles as well as the ablation threshold, the ablated mass, and the particle size were investigated. The ablation plume was made visib

BACKGROUND: The study describes a quantitative and systematic investigation of the collateral thermal damage during infrared photoablation as a function of wavelength between 2.7 and 6.7 µm. METHODS: Using the tunable Free Electron Laser at Vanderbi

The ablation depth and collateral thermal damage for pulsed infrared photoablation as a function of wavelength with the free-electron laser (FEL) at 10.1, 11.8, 12.8, and 14.5 mm wavelengths is investigated. FEL data are compared with the blow-off an

The knowledge of the kinetics and the density of the ejected particles can lead to a better understanding of the photoablation process. Therefore, the dynamic behavior of thermal laser ablation (initial velocity of ejected particles v0, recoil moment

Thermal keratoplasty is currently performed with a Ho:YAG laser at 2.1 micrometer wavelength. Long term stability critically depends upon the coagulation depth of each cone and thus upon emission wavelength, absorption and focusation, all contributin

Pulsed IR laser ablation on dental hard substances was studied in the wavelength range between 9.5 and 11.5 micrometers with the Free-Electron Laser (FEL) in Nieuwegein/NL and between 6.0 and 7.5 micrometers with the FEL at Vanderbilt University in N

An ablation model for pulsed laser ablation, based upon Lambert's law is presented. Ablation is assumed to be entirely the result of heating and subsequent evaporation of tissue water. The model predicts the ablation depth per pulse as well as the co

Wavelengths in the range from 12 micrometers up to 70 micrometers (far IR) have a water absorption coefficient in the same order as wavelengths used successfully for ablation near the 6 micrometers water absorption peak. Thus these wavelengths were c
