Objectives : Recently, He-Ne laser has been used for clinical purpose. We study the medical basis of He-Ne laser therapy and We make a proposal concerning the clinical application of using He-Ne laser in Medicine. Methods : We have selected data related to He-Ne laser therapy and study how to use He-Ne laser in clinic. Results : In biology, He-Ne laser therapy has been effects of an improve in skin regeneration an improve in peripheral and central nerve regeneration an improve in muscle regeneration, an anti-inflammation an alleviation of pain and a bone repair. In oriental medicine, He-Ne laser has been used to laser acupuncture and laser oriental physical treatment. In clinic, He-Ne laser have been used to care several parts like as facial palsy, facial spasm, trigeminal neuropathy, rhinitis and tinnitus. Recently, there is argument that He-Ne laser therapy is suitable to medical insurance. Conclusions : Laser therapy in oriental medicine is widespread and We can apply He-Ne laser to facial palsy, facial spasm, trigeminal neuropathy, rhinitis, tinnitus by using laser acupuncture or laser oriental physical treatment. Till now the whole mechanisms are not fully understood, so we hope to study these mechanisms actively and make suitable to medical insurance device in the near future.

In this study, we analyzed the luminous efficiencies of Ne-Xe-Ar and He-Ne-Xe-Ar mixing gas in compared with those of Ne-Xe and He-Ne-Xe mixing gas to improve luminous efficiency by adding a small amount of Ar gas. At the Xe 4%, the brightness of Ne-Xe and He-Ne-Xe mixing gas is higher than others. As the Xe % increases, power consumption decreases. Thus, in the Ne-Xe and He-Ne-Xe mixing gas of Xe 4%, we obtained maxium luminous efficiency. The Ar concentration is varied from 0.1% to 0.7% in this study. The luminous efficiency of the Ne-Xe(4%) mixing gas is improved to 1.16 and 1.13 lm/W by adding an Ar concentration of 0.4% and 0.5%, respectively. The luminous efficiency of the He-Ne-Xe(4%) (He : Ne = 7 : 3) mixing gas is considerably improved by adding an Ar concentration of above 0.3%. The maximum luminous efficiency of this mixing gas is 1.38 lm/W at the condition of adding an Ar concentration of 0.5%.

Two kinds of the ac-plasma display panel (PDP) with the comb type and the matrix type electrodes were fabricated. The discharge properties were studied as a function of as species (Ne and Ne+He+Xe) and its pressure. The firing voltages (Vf) of the PDP with comb type electrodes were 159 V and 195 V under pure Ne and ne+He+Xe(68:30:2) gas mixture respectively. In case of PDP cell with the matrix type electrodes the Vf was increased to 200 V for pure Ne and 240 V for Ne+He+Xe gas mixture under the same gas pressure(300 mbar).

In order to determine the effect of intravenous He-Ne laser irradiation, values of serum total cholesterol, Triglyceride, LDL-cholesterol and HDL-cholesterol were measured. Twenty three patients with hyperlipidemia who visited Gunpo Oriental Medical Center of Wonkwang University were treated with He-Ne laser irridiation and analyzed by Paired T-test of SPSS program. The following results were obtained : The serum Total cholesterol and LDL-cholesterol of patients treated with He-Ne laser irradiation showed a significant(P<0.05) decrease, and the serum Triglyceride and HDL-cholesterol of patients treated with He-Ne laser irradiation showed no significant(P<0.05) effects.

We examined ($He_x-Ne_{l-x}$)-Xe gas discharge in an AC PDP cell by computer simulation to understand the gas mixing effects. The breakdown and sustain voltage were significantly lowered with the addition of Ne into He-Xe. The luminance and efficiency in ($He_x-Ne_{l-x}$)-Xe also improved when compared with the He-Xe or Ne-Xe gas mixture. The luminance is maximum around $30{\sim}40%$ He addition, while the efficiency shows peak values at 70% He. Two-dimensional numerical simulation was done to explain these results.

현재 플라즈마 디스플레이에 이용되는 He-Ne-Xe 이원가스의 단점을 상호보완하기 위하여 He-Ne-Xe 혼합가스의 방전특성 실험을 수행하였다. Xe(5%)에서 He:Ne의 혼합비는 3:2일 때 최적의 휘도와 구동전압, 색순도를 갖는 것으로 나타났으며, Xe의 혼합비의 대해서는 Xe의 혼합비가 증가할수록 휘도와 색순도가 향상되었으며 구동전압은 높아졌다.

This paper describes preliminary discussions on manufacture of a He-Ne laser and investigation of output characteristics. The He-Ne laser which is to be manufactured is what is the most common wavelength λ=632.8[nm] transition in the red portion of the spectrum. The output characteristics as various parameters, such as gas mixture ratio, gas pressure, discharge current, resonator, resonator length, and the efficiency characteristics as a input power will be investigated.

본 논문은 헤테로다인 간섭계를 이용한 레이저 진동 측정기에 대해 기술하고 있다. 상용 레이저 진동 측정기가 대부분 AOM을 이용하여 주파수 천이를 일으키는 반면, 본 연구에서는 Zeeman 안정화 He-Ne 레이저를 사용하므로써, 서로 다른 주파수를 가지는 레이저를 동시에 얻을 수 있었다. 따라서, Zeeman 안정화 He-Ne 레이저를 사용하는 진동측정기의 경우 간섭계 구성을 위해 사용되는 비용을 현저히 줄일 수 있다. 또한, AOM의 고주파 신호를 처리하기 위해서는 RE 대역의 신호처리 회로 설계가 필요하지만, Zeeman 안정화 레이저의 주파수 천이가 낮으므로, 제안된 진동측정기의 신호처리가 용이하다.(중략)

국내 및 해외에서 생산 되는 윤활유에 Cloud-point curves 및 상용성 개념을 도입하여 이러한 데이터를 측정할수 있는 장치를 기존의 Light scatering, Neutron scatering, Visible Method등이 아닌 He-Ne Laser를 이용하여 측정하는 장치이다. He-Ne Laser을 이용하여 공중합체 용액의 Cloud-point curves를 측정하였고, 측정 Cloud-point curves 데\ulcorner를 연속열역학적 상평형관계식에 적용 coex istence curves를 추산하였으며 추산치와 측정치를 비교 검토하였다. 멀지 않은 해에는 이러한 분석장치가 상용화되어 윤활유 제품의 상용성을 평가하는 장치가 될 것으로 사료된다. 따라서, 기존 윤활유 제품 및 신제품의 상용성(compatibility)을 He-Ne Laser을 이용하여 측정하고 다른 일면으로는 윤활유 제품의 고품질화 및 제품의 경쟁력을 강화하는데 커다란 영향을 미치리라 사료된다.

The optimal mixing condition of four components gas(Ne,Xe,He,Ar) in PDPs was caculated by a numerical simulation method. The dominated reactions in which $Xe^*(^3P_1)$ is produced and decays were investigated in three components gas (Ne,Xe,He) and our new components gas (Ne,Xe,He,Ar). A peak point of $Xe^*$ density appears in the range of 0.1% to 2% of Ar mixture ratio. The results of simulation show that the direct exitation of Xe by electrons has the greatest influence on the inceasing $Xe^*$ density in both gas mixtures.
