The effect of continuous low-power He-Ne laser on the hatching rate and life span of Artemia urmiana
Artemia, as live food, is of vital importance in aquaculture. In this study, we have studied the helium-neon (He-Ne) laser beam with 10 mw on the hatching and life span of Artemia cysts. He-Ne laser irradiation was performed with a 10 mw power at 3, 4 and 5 h irradiation periods. Cysts were hatched by standard method. Hatching percentage after 4 h of irradiation was more than other treatments a...
متن کاملComputational Complexity Since 1980
The field of computational complexity is reaching what could be termed middle age, with over forty years having passed since the first papers defining the discipline. With this metaphor in mind, the early nineteeneighties represented the end of adolescence for the area, the time when it stopped wondering what it would be when it grew up. During the childhood period of the sixties, research cent...
متن کاملFrequency doubling of He–Ne laser radiation at 632.8 nm
Second harmonic generation (SHG) obtained using a potassium dihydrogen phosphate (KDP) nonlinear crystal from a CW He–Ne laser as a pump source, which emits at 632.8 nm, is reported. The SHG efficiency at the power of the He–Ne laser utilized (18 mW) and the fundamental beam waist available (0.1 mm), was evaluated theoretically; the same efficiency was measured experimentally obtaining a value ...
متن کاملStatistical Analysis of Instantaneous Effect of Polarized He-Ne Laser Radiation on the Elastic Modulus of Soft Biological Tissue
Introduction: This work is dedicated to investigating the effect of applying polarized He-Ne laser beam (λ= 632 nm, 10 mW, 1 j/cm2) with polarization direction perpendicular to the stress direction on the tensile strength of biological tissue (elasticity index of the Pleura 10*4*0.1 mm). Method and Material: The optimized characteristics of the laser illumi...
متن کاملE. K. A. ADVANCED PHYSICS LABORATORY PHYSICS 3081, 4051 THE He-Ne LASER AND OPTICAL RESONATORS
A laser produces electromagnetic radiation which is both spatially coherent and of narrow spectral width via a mechanism known as Light Amplification by Stimulated Emission of Radiation. The first working laser was developed in 1960 by Theodore Maiman at Hughes Research Laboratories. Since then laser technology has proliferated, with uses in industry, medicine, research, military and law enforc...
