Enhanced Control of Transient Raman Stering Using

In a molecular-monoatomic gas mixture, the inverse Raman lifetime can be written as: 11TApBpCp2RRB[MHz] , (2) where pR and pB are respectively the partial pressures of the Raman-active and buffer gases, A is the diffusion-limited broadening coefficient, B is the collisional self-broadening coefficient and C is the cross-broadening coefficient.

Comparison of dielectric breakdown properties for

Among the three buffer gases, CF 4 has a largest impact on the EEDF of gas mixtures. The mixing of CF 4 reduces more electrons with low energy than CO 2 and N 2. In addition, as a buffer gas, CF 4 makes insulating mixtures depend more linearly on the content of buffer gas than CO 2 and N 2.
