The absorption spectrum of a new crystal Nd:Sr-5(PO4)(3)F (Nd:S-FAP) w
as measured and its strong absorption peak at 805.4 nm showed that it
can be suitably pumped with a laser-diode. By using a laser-diode pump
operating at 805.4 nm, Nd:S-FAP has been successfully lased at 1.059
mu m. A slope efficiency of 37.5% and a laser threshold of only 13 mW
have been measured, and the theoretical prediction is in agreement wit
h the experimental result.
