The AC3-808B and AC3-808BW series of high-brightness 30W 808 nm fibre laser pump sources arebased on high-reliability single-emitter (SE) laser diodes.
The new third-generation 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 technology for wavelength stabilization minimises 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 685µm fibre bundle with 0.15NA gives higher brightness and easy 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 users such as material cutting and processing, light welding, marking and printing.
