    "abstract": "We describe the operation of two GaN-based diode lasers for the laser\nspectroscopy of gallium at 403 nm and 417 nm. Their use in an external cavity\nconfiguration enabled the investigation of absorption spectroscopy in a gallium\nhollow cathode. We have analyzed the Doppler broadened profiles accounting for\nhyperfine and isotope structure and extracting both the temperature and\ndensities of the neutral atomic sample produced in the glow discharge. We have\nalso built a setup to produce a thermal atomic beam of gallium. Using the\nGaN-based diode lasers we have studied the laser induced fluorescence and\nhyperfine resolved spectra of gallium.",
