Abstract:
A self-pumped mirror was implemented experimentally for CO2 laser radiation generated by a four-wave interaction with feedback in CCl4 and SF6. The lowest threshold energy of the input signal was ~8 mJ for CCl4 and ~2 mJ for SF6. The energy reflection coefficient was 5 for CCl4 and 11 for SF6. The maximum energy of the output radiation exceeded 0.2 J.
