Abstract
Hollow-core capillary discharge lamps on the mm or sub-mm scale are provided. The hollow-core capillary discharge lamps achieve an increased light intensity ratio between 194 mm (useful) and 254 mm (useless) light than conventional lamps. The capillary discharge lamps may include a cone to increase light output. Hollow-core photonic crystal fiber (HCPCF) may also be used.
