Abstract
A green up-conversion laser is demonstrated in a 120 mu m diameter microsph ere of Er3+-doped ZBLAN at room temperature. Lasing occurs around 540 nm wi th a 801 nm diode laser pump. The lasing threshold of only 30 mu W of absor bed power is over two orders of magnitude lower than the lowest previously observed in IR-visible up-conversion lasing [1].
