Abstract
A green room temperature up-conversion laser has been demonstrated in a 120 mu m diameter microsphere of Er3+ doped ZBLAN. Lasing occurs around 540nm with a 801nm diode laser pump. The lasing threshold of only 30 mu W of abso rbed power is over two orders of magnitude lower than the lowest previously observed.
