nm-pumped Tm-doped fibre lasers provide a number of distinct benefits for integration into next generation DIRCM systems. Incorporation of Tm-doped fibre technology into mid-IR laser systems has been demonstrated in two main architectures to date; in early works the fibre laser was used as a low quantum defect pump source for Q-switched solid- state holmium laser which was subsequently shifted to the mid-IR using a ZnGeP2 OPO (1) and more recently, a pulsed fibre laser systems was used for directly pumping the OPO (2). He we present two fibre laser systems for integration into DIRCM systems. Firstly we present a 70W MOPA system (pump power limited) operating at 1908nm with 53% slope efficiency from the amplifier stage for pumping Ho:YAG. Secondly we present a pulsed fibre laser system producing over 4kW peak power at 1910nm using all single-mode fibres. |
