MR-guided LITT is a safe and effective treatment modality that improves survival in well-selected patients who have liver metastases. A major advantage of MR-guided LITT is that it can be easily performed under local anesthesia in an outpatient setting with a low complication rate.

Archives of Ophthalmology, 1987
To the Editor. —The article by Nanevicz et al,1in the December 1986 issue of theArchives, is of interest, as we also have an interest in the concept of using pulsed ultraviolet (UV) radiation for the removal of cataractous lenses. We agree with the authors that there are "significant challenges in developing an appropriate endocular delivery system ...

Lasers in Surgery and Medicine, 1988
AbstractThe bone ablation characteristics of five infrared lasers, including three pulsed lasers (Nd:YAG, λ = 1,064 μm; Hol:YSGG, λ = 2.10 μm; and Erb:YAG, λ = 2.94 μm) and two continuous‐wave lasers (Nd:YAG, λ = 1.064 μm; and CO2, λ = 10.6 μm), were studied.

Superresolved femtosecond laser ablation
Optics Letters, 2007The determinist behavior of the femtosecond ablation process allows morphing features well under the diffraction limit by utilizing the thresholding effect, down to the nanometer scale. Because there are a vast range of applications where scaling down the size of the features is a major concern, we investigate the use of superresolving pupil plane ...

Laser trabecular ablation (LTA)
Lasers in Surgery and Medicine, 1991AbstractAs part of a pilot study for glaucoma surgery, the use of 3 infrared solid state lasers with 4 fiber optic delivery systems to ablate human trabecular meshwork was investigated. Laser trabecular ablation (LTA) was attempted with the Erbium:YAG (2.94 μm), Erbium:YSGG (2.79 μm), and Holmium:YSGG (2.1 μm) lasers.

Laser Ablation and Laser-Hybrid Ablation Processes: A Review
Materials and Manufacturing Processes, 2015Laser beam machining (LBM) has proven its applications and advantages over almost all the range of engineering materials. It offers its competences from macro-machining to micro- and nano-machining of simple-to-complex shapes. The hybrid approaches in laser ablation have demonstrated much improved results in terms of material removal rate, surface ...

Laser Ablation of Solid Materials, Laser Ablation Propulsion
2021The analysis of laser pulse effects on polymers is presented as applied to laser ablation propulsion. Polymers of CHO-chemical composition are considered to use as propellants to increase the efficiency of LAP by burning of polymer vapors and producing such combustion components of this reaction as CO2 and H2O.

Laser ablation occurs when high fluence, short wavelength laser radiation interacts with attenuating materials. A problem that dogs laser ablation machining in the industrial theatre is debris: solid, melt and vapour are all generated. This is a problem borne of micro-particulate debris and van der Waals, electrostatic and capillary forces, to strongly

Lasers for Pulsed Laser Ablation
2013In this chapter, several lasers (e.g. Nd-YAG laser, Ti-sapphire laser, excimer laser, \(\text {CO}_{2}\) laser) are analysed because they are versatile sources of energy in a highly concentrated form, being attractive tools and research instruments for a large variety of research and production fields, and for laser ablation in particular.

Abstract Laser ablation sampling provides significant benefits and capabilities for chemical analysis. It represents one of the most promising technologies for direct solid sample introduction. Despite the advantages, there are a number of issues that should be addressed to better understand and utilize this technology.
