Abstract


Some Characteristic on Profile of a He-Ne Laser generating simultaneously at λ=6328Aˇ and hfs on Ne at <3S_2-2P_4> has been made by the use of a pressure Su\canning Fabury-Perot interference Spectrometer which has resolving power of the instriment was 3.1X10^5.
The necessary Condition to lead laser threshold in the confocal resonator are given by the following formulas.
g(ν) L≥1-γ
or, N_2-g2/g1-N_1≥√16π^3/ln2Δν_D1/Lλ^2A_2A_21
where g(ν) is gain Confficient, K, distance between the mirrors, r, reflectance of mirror, A_21: Probability of transition, Δν_D, resonance amplitude, and g_1, g_2, parameters.
The first experimental results measured under the higher-order resolving Power (R_t≒3^4X10^5) is quite close that of values Calculted from A.L. Oshirovich and Ya.F. Veralainen data, and also, the second resulte on hfs of Ne at λ=6238Aˇ is quite colse to that of the experimented results (by Yoh-Han Paot)
