Abstract The spin-flip Raman (SFR) laser is shown to be an excellent tool to investigate different processes in the conduction band of the SFR laser crystal itself. For the case ofn-InSb, intracavity spectroscopy of inter-Landau transitions is demonstrated to be much more sensitive than conventional transmission spectroscopy. Data on cyclotron harmonic transitions, both free and LO-phonon assisted, are obtained from the output power characteristics of the SFR laser versus magnetic field. The spin-splitting energy and the effectiveg-factor up to 14 T are derived from the SFR laser frequency. The influence of temperature on SFR laser power, threshold and frequency is investigated. The relaxation following the SFR laser pulse is observed in the electrical conductivity. This yields in a direct way the spin-lattice relaxation time at high magnetic fields, which is of the order of 200 ns.
