ABSTRACT
This work presents what we believe is a new way to use a CTHYAG crystal for spontaneous emission instead of laser emission. The spontaneous emission is collected in one main direction thanks to a luminescent concentrator configuration. The CTHYAG is indirectly LED-pumped by a CeYAG delivering 3.5â
ms pulses at 10â
Hz with an energy of 2 J in the visible (550-650â
nm). In a configuration optimized for light extraction, the CTHYAG luminescent concentrator provides a broadband emission between 1.8 µm and 2.1 µm with a unique combination of power (1 W) and brightness (21.2 W/cm2/sr) that could be useful for short-wave infrared (SWIR) lighting applications.
