Creating a Cavity-Dumped Helium Neon Laser
We use an acousto-optic modulator to quickly extract circulating optical power from a homebuilt 1.4 m open-cavity helium neon oscillator. We can extract 100 ns pulses with a maximum peak power of approximately 2 mW at a repetition rate of 100 kHz. We can attain repetition rates of over 1 MHz with decreased peak power. This work was supported by the Laser Teaching Center at Stony Brook Universit...

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
15 صفحه اولEffect of a helium-neon laser on cutaneous inflammation.
A Helium-Neon (He-Ne) laser with a wavelength of 632.8 nm is known to have photobiological effects and is widely used for reducing the pain of herpes zoster and accelerating wound healing, however the cellular mechanism and effect of the He-Ne laser are poorly understood. The present study was designed to examine the influence of He-Ne laser irradiation on irritant and allergic contact dermatit...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولDeflection of carbon dioxide laser and helium-neon laser beams in a long-pulse relativistic electron beam diode
Deflection of carbon dioxide and helium-neon laser beams has been used to measure plasma and neutral density gradients during the operating mode and after the shorting time of a long-pulse field-emission electron beam diode. Plasma density gradients of (10’4-10’5) cme4 were observed throughout the diode during the fmal microsecond of the 2-3 ps electron beam pulse. The neutral density gradient ...
