Pulsed InSb Spin-Flip Raman Laser

A study of pulsed InSb spin-flip Raman laser, using TE CO and CO2 lasers as pumping sources, is reported. Pumping wavelength dependences of magnetic tuning and output power were investigated, and magnetic tuning characteristics were also studied for the samples with different carrier densities. Effective g-factor of conduction electron in InSb was estimated from the measured frequency shift. Furthermore, absorption spectra of NO gas were observed with this pulsed spin-flip Raman laser.
