dc.description.abstractMilliwatt average power terahertz quantum cascade lasers (THz-QCLs, 2 THz to 5 THz) have been developed for spectroscopy and as local oscillators for heterodyne receivers. Novel DFB THz-QCLs have been fabricated and show single-mode operation. The narrow line widths of <10 MHz and stark shift tuning of of 6 GHz, allows for wavelength modulation spectroscopy of low pressure gasses in the unexplored THz frequency band. The same devices also act as local-oscillators for heterodyne receivers for remote-sensing and astronomy. Lastly we report on improved tunable DFB devices for use in spectroscopy.en_US
