Abstract:
An unsaturated continuous-wave output power of 109 mW was
produced from a diode-pumped Ho3+-doped double-clad silica fibre
laser that did not require the use of a sensitiser. The laser operated with
a slope efficiency of 7% and an emission wavelength of 2.14 mm.
Energy transfer upconversion may have adversely affected the performance
of the laser.
