Paper Abstract

The main characteristics of the laser radiations are: directivity, monochromaticity and spatially and temporally coherence. Using the aggregation state as a criterion for classification, we describe solid, liquid and gaseous active media. Concerning the methods used to realize the population inversion, we also describe: optically, electrically and high energy particles pumped lasers. Depending on the laser media and the mode of excitation, a laser may operate in multiple ways: the continuous-wave operation, the long-pulsed operation, the Q-switched mode of operation and the mode-locked operation. The interaction of laser radiations with the living matter is based upon four main effects: the thermal, mechanical, electrical and biological effect. The main field of therapeutical use of lasers are: the management of lid tumors and intraocular tumors, dacryocystorhinostomy, the treatment of diabetic retinopathy, thromboembolic retinal syndromes, inflammatory choriretinal disease, chorioroetinal degenerations, retinal angimatosis, retinal breaks and retinal detachment, corneal diseases, glaucoma, lens diseases. Laser has also nontherapeutical applications in diagnosis and prognosis of ophthalmologic diseases.
