We have directly monitored the rf Stark-field-induced splitting of the gain profile of the μm 13CH3F optically pumped far-infrared (OPFIR) laser transition. The resulting data are found to be in good agreement with ac Stark theory. Comparison with dc Stark tuning techniques shows that the rf Stark effect possesses a number of attractive attributes for frequency tuning cw OPFIR lasers. We propose the far-infrared and terahertz emitting diodes (FIR-EDs and THz-EDs) based on the graphene-layer/black phosphorus (GL/b-P) and graphene-layer/MoS2 (GL/MoS2) heterostructures with the lateral hole and vertical electron injection and develop their device models. In these EDs, the GL serves as an active region emitting the FIR and THz photons. Depending on the material of the .
Methanol and its isotopic species have been systematically investigated as sources of far- infrared (FIR) laser emission utilizing a newly designed optically pumped FIR laser system. The system combines several different FIR laser cavity designs with the extended line coverage available from a recently developed high-resolution CO 2 laser of.

This report summarizes studies on optically pumped far infrared molecular gas lasers. The research has been concerned with the general subjects of far infrared integrated optics and technology, the discovery of new optically pumped molecular laser systems, and the study and analysis of nonlinear processes (Raman and hyper-Raman) that can occur in optically pumped systems.
