The effects of argon laser light on endotracheal tubes and gas mixtures have been studied. In recommended use accidental exposure to red rubber and PVC tubes caused minimal damage. Prolonged exposure of PVC tubing and a 2:1 nitrous oxide:oxygen mixture produced a minimal increase in temperature and no detectable increase in the concentration of higher oxides of nitrogen. Transparent endotrachea...

BACKGROUND To evaluate the long-term outcomes of Argon laser photocoagulation compared to surgical direct cyclopexy in small-size cyclodialysis cleft patients. METHODS This is a retrospective study. Small-size cyclodialysis cleft patients who underwent Argon laser photocoagulation and surgical direct cyclopexy were reviewed. The mean follow-up period were 82.4 (range, 61 - 145) months and 99....

PURPOSE To evaluate the role of argon laser as an adjunctive therapy in ten patients with resistant infected corneal ulcers with or without hypopyon. METHODS The study included 20 patients, split into two groups of ten, with resistant infected corneal ulcers with or without hypopyon. One group was considered as the control group and treated with local and systemic specific antimicrobial drugs...

We present a cryogenic source of periodic streams of micrometer-sized hydrogen and argon droplets as ideal mass-limited target systems for fundamental intense laser-driven plasma applications. The highly compact design combined with a high temporal and spatial droplet stability makes our injector ideally suited for experiments using state-of-the-art high-power lasers in which a precise synchron...

A 42-year-old woman was admitted to Mersin University, Department of Ophthalmology Clinic with itching and burning sensation of the right eye for 3 weeks. In her slit-lamp examination, nits and lice, attached to the upper and lower eyelashes of her right eye, were observed. Lice and nits were destroyed by argon laser phototherapy and were removed with the help of a fine forceps thereafter. Argo...

OBJECTIVE To determine the efficacy of argon laser punctal stenosis inpatients with contact lens-induced dry eyes. METHODS A retrospective review of 25 eyes of 13 patients who underwent argon laser punctal stenosis to improve their contact lens intolerance was performed. The mean age was 31 (range, 21-52) years and 11 patients (85%) were women. The mean Schirmer I test was 15.2 (range, 3-35)....

Optical emission spectroscopic studies of laser-created argon sparks are carried out. Pulses of 532 nm and 8 ns from a frequency-doubled Nd:YAG laser are used to create an argon spark at 1 atm. Gated photography of 2 ns is used to investigate spark evolution at early times. Electron temperature and density measurements are made from the spectral data. The Stark broadening of emission lines is u...

purpose: to determine the effect of grid pattern laser photocoagulation on diabetic diffuse macular edema with assessment of visual outcome. patients & methods: the author reviewed the medical records of 84 eyes of 62 patients with diabetic diffuse macular edema treated with grid pattern green argon laser photocoagulation in farabi eye hospital between the years 1992-1995, the follow-up period ...

We report on the development of a crystal spectrometer for experiments with helium-like argon ions as a target. The spectrometer will be used as a precise diagnostic tool to study a) collisions between relativistic highly charged ions and argon atoms at the ESR; b) the interaction between pulses from the PHELIX laser and large argon clusters; and c) studies of He-like argon as created in the SP...
