Alfalight high-brightness 30W 808nm fibre laser pump sources

 

New from Alfalight, and available from Pacer, is the AC3-808B and AC3-808BW series of high-brightness 30W 808nm fibre laser pump sources based on high-reliability single-emitter (SE) laser diodes.

New from Alfalight, and available from Pacer, is the AC3-808B and AC3-808BW series of high-brightness 30W 808nm fibre laser pump sources based on high-reliability single-emitter (SE) laser diodes. 

The combined power modules (CPM III) provide over 20,000 hours MTTF and do not suffer the catastrophic failure mode inherent in conventional bar-based emitters. 

Alfalight's proprietary technology for wavelength stabilisation is designed to minimise wavelength shift over temperature, enabling air-cooled operation.

The CPM III series modules combine seven single-emitter diodes to provide 30W of 808nm fibre-coupled light output.

Use of a 685[micro]m fibre bundle with 0.15NA gives higher brightness and allows for incorporation into an existing fibre-coupled bar based 0.22NA systems.

Target markets include industrial end-pumped DPSS lasers for Nd:YAG or Nd:YVO4 systems for end uses such as material cutting and processing, light welding, marking and printing.
