Free beam laser endarterectomy (LE) and contact laser endarterectomy (CLE) were compared in 15 arteriosclerotic New Zealand white rabbits. The rabbits underwent balloon catheter trauma to the thoracoabdominal aorta and were fed a 2% cholesterol diet for 18 weeks. Thoracoabdominal exploration was performed under general anesthesia and multiple endarterectomies were performed in each rabbit. Athe...

The argon laser set at 50 mum, 100-150 mW, o-2 s occluded corneal blood vessels in pigmented Dutch rabbits provided the corneal responsible for inducing vascularization was inactive. After arterial treatment with the argon laser retrograde flow in untreated veins was demonstrated by fluorescein angiography. Therefore all corneal new vessels should be treated, not just arteries. Minimal iris dam...

Experiments on microwave scattering from resonance enhanced multiphoton ionization (RADAR REMPI) are presented for argon (3+1 REMPI), xenon (2+1 REMPI) and nitric oxide (1+1 REMPI) to demonstrate its capabilities for nonintrusive diagnostics. The time evolution of the microwave scattering from 3+1 REMPI in argon with different frequency tripled Ti:sapphire laser pulse energies at different pres...

The purpose of this study is to evaluate the success rate and safety of argon laser photocoagulation as a modality of treatment for symptomatic trichiasis in a Middle Eastern country (Jordan). This simple descriptive study included 54 patients (68 lids) with symptomatic trichiasis. They were treated with argon laser and followed over 8 month period. After topical and infiltration anaesthesia, 3...

The performance of a new pulsed arc cluster ion source (PACIS) is demonstrated for pure metal cluster ions and anions as well as mixed metal-rare-gas clusters. Pure metal clusters like W$ exhibit intensity distributions similar to those from laser vaporization sources. The ion current of the PACIS is comparable to that of a laser vaporization source. For metal-doped argon cluster ions, a single...

Short intense laser pulses of visible and infrared light can dramatically accelerate crystal nucleation from transparent solutions; previous studies invoke mechanisms that are only applicable for nucleation of ordered phases or high dielectric phases. However, we show that similar laser pulses induce CO(2) bubble nucleation in carbonated water. Additionally, in water that is cosupersaturated wi...

PURPOSE In Asian countries, laser iridotomy for the treatment of angle-closure glaucoma is a common cause of bullous keratopathy, which may be associated with a shallow anterior chamber and dark iris pigmentation in Asians. Several cases of corneal decompensation after argon laser iridotomy have been reported. In the present study, we evaluated the harmful effects of argon laser iridotomy on th...
