Laser Pump Diodes 


30W Fibre Coupled High Power Laser Diode Bars (808nm)

These fibre-coupled diodes, manufactured by Spectra Physics in 2004 - 2005, consist of a diode laser bar (linear array) made up of number of individual emitters, each coupled in to a small diameter fibre. The individual fibres form a low NA fibre bundle, offering a low cone angle and high brightness output.

With an operating wavelength around 808nm, these diodes are suited to pumping Nd:Yag or Nd:VO4 solid state lasers. They can be temperature tuned (within the operating temperature window of 20oC to 35oC) and have typical wavelength/temperature coefficient of 0.2-0.3nm/ oC. Our stock includes devices with a centroid wavelength at a thermistor temperature of 30oC in the range from 805.5nm to 811.0nm.

We have the manufacturer’s original test data for many of the diodes that we have in stock.

40W FAC Laser Diode Conduction Cooled Single Bar Package

Manufactured by Coherent Inc. in 2006 under part number B1-808-40C-19-30 A/L, these 1cm long bars have 19 emitters with a 30% fill factor. They emit at 808 +/-3nm when operated at 30oC. The bar is fitted with a lens to provide fast axis collimation. The unit must be mounted on an appropriate heatsink to remove heat.
