Abstract

We calculated the group velocity of a probe pulse located at the gain center of five-level CH ₃F far-infrared molecular gas amplifier as a function of pump beam intensity and pressure. The results indicate this large class of optically pumped molecular system can exhibit significant group velocity reduction over a broad range of the electromagnetic spectrum. The group velocity can be further controlled by using the rotational sublevel splitting in a Stark static electric field in conjunction with optical pumpings.
