A new method of laser parameter analysis is proposed in which gain parameter G₀, saturation irradiance I_s and a measure of partially homogeneous broadening m are readily determined by measuring the output powers of a traveling-wave-type laser oscillator twice for different intracavity losses without using any probe laser. Applying this scheme to a He–Ne 3.39 µm laser oscillator with a CH₄ gas cells as a variable attenuator, G₀=0.417 m^-1, I_s=1.36 mW/mm² and |m|=0.710 (the ratio of the Lorentzian to Doppler line widths, i.e. Δν_L/Δν_D≃0.604) are obtained under 14 mA discharge current of the laser.
