NH3 laser THz emission under optical pumping by "long" (-100 vs) CO2 laser pulses
Chinese Optics Letters(2023)
摘要
Terahertz (THz) NH3 lasing with optical pumping by electron-beam-sustained discharge "long" (-100 vs) CO2 laser pulses was obtained. The NH3 laser emission pulses and the "long" pulses of the CO2 pump laser were simultaneously measured with nanosecond response time. The NH3 lasing duration and its delay with respect to the pump pulse were measured for various CO2 laser pulse energies. For the CO2 laser pump line 9R(30), three wavelengths of 67.2, 83.8, and 88.9 vm were recorded. For the CO2 laser pump line 9R(16), only a single NH3 laser line with a wavelength of 90.4 vm was detected.
