The authors report on wide-band tunable stimulated radiation (SR) in the near-IR range from La/sub 3/Ga/sub 5/SiO/sub 14/-Cr/sup 3 +/. The lasing spectrum parameters of La/sub 3/Ga/sub 5/SiO/sub 14/ and some of the most extensively studied oxygen and fluorine crystals containing Cr/sup 3 +/ are shown. Luminescence excitation spectrum is shown for Cr/sup 3 +/ in La/sub 3/Ga/sub 5/SiO/sub 14/. The authors attain and examine SR on a vibronic transition in Cr/sup 3 +/ in trigonal La/sub 3/Ga/sub 5/SiO/sub 14/ at 300 K and obtain the widest smooth SR tuning wavelength range for any inorganic material containing octahedral Cr/sup 3 +/ ions.
