Resonant enhancement of the output power of a He–Ne laser due to modulation of the discharge current

V. V. Tuchin, G. G. Akchurin


Abstract: It was found experimentally that the output power of an He–Ne laser ( λ = 0.63 μ) increased resonantly when the discharge current was modulated at a frequency f_m ≈ 60 kHz. This was attributed to a redistribution of the electrical properties of the gas-discharge plasma as a result of an artificial excitation of striae in the discharge. The possibility of using this phenomenon in the control of the output power of gas lasers was considered.
