Terahertz wide range tunable cyclotron resonance p-Ge laser

We present a Terahertz (THz) p-Ge laser operating in a cyclotron resonance (CR) mode. Thanks to the use of the optimum crystallographic orientation of p-Ge with respect to crossed E⊥B fields, the laser line frequency is continuously tunable in the range 1.2–2.8 THz (40–90 cm−1) with the linewidth be...

Zusammenfassung:We present a Terahertz (THz) p-Ge laser operating in a cyclotron resonance (CR) mode. Thanks to the use of the optimum crystallographic orientation of p-Ge with respect to crossed E⊥B fields, the laser line frequency is continuously tunable in the range 1.2–2.8 THz (40–90 cm−1) with the linewidth being 6 GHz (0.2 cm−1). We also show that due to such a wide CR radiation range, the laser can serve as a base for a THz spectrometer.
