Frequency 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 کاملThe 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 کاملاندازهگیری ضریب نفوذ‌پذیری حرارتی محلول نانوذرات طلا با استفاده از پرتودهی گاما
Thermal diffusivity of Au nanofluid was measured by using a dual beam mode-mismatched thermal lens method. The samples were prepared in various sizes by utilizing the gamma radiation method. In the dual beam mode-mismatched thermal lens, a diode laser (532 nm) was used as an excitation beam and a He-Ne laser with the beam output at 632.8 nm was used as a probe beam. Thermal diffusivity of gold...
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 کاملStabilization of internal-mirror He-Ne lasers.
Simultaneous frequency and amplitude stabilization of a commercial internal-mirror He-Ne laser by a new simple method is reported. In this method, the back beam intensity of one polarization of the orthogonally polarized modes is fed back as a heater current to control the cavity length of the laser. The relative frequency stability and amplitude stability achieved are, respectively, +2.5 X 10-...
