Intense has released prototype versions of its next generation Series 8000 793nm high power pump laser diode module. The new multi-emitter pump module delivers 20W of output power from a 105µm core fibre, 0.15 or 0.22 numerical aperture. It is designed to meet growing demand for laser pumps in the field of eye-safe, thulium-doped fibre laser systems. The pump module is used in defence and aerospace applications, such as lidar and direct infrared countermeasures, and to replace existing diode pumped solid-state (DPSS) technology in medical and industrial applications.
The Series 8000 793nm standard mini-fibre packages (MFP) provide a robust and cost effective solution for applications with power requirements in the 4-5W range. The same high power chip technology used in Intense's 793nm MFPs is now available in new multi-emitter packages designed to yield a maximum optical pump power of up to 20W. The building block 4-5W laser diodes can also be supplied in free space configuration on C-mount with a FAC-lens, or on isolation sub-mounts.
