摘要：
We report an enhanced supercontinuum generation (SCG) from a rare-earth (Pr3+) doped low bandgap zinc borate glass when excited with 60 fs pulses from a Ti-sapphire laser. The emission associated with the absorption bands due to Pr3+ doping (around 420-500 and 580-600 nm) is observed to assist the enhanced SCG. (C) 2021 Optical Society of America
