Single Bar Diode Laser

Product image of Single Bar Diode Laser

Conduction-cooled single bars are well introduced in the market and are an industry standard in terms of size and footprint. At Coherent, these laser bars are available in a very wide range of wavelengths and powers, with optional beam shaping such as fast-axis collimation, both-axis collimation, or even further focused to a defined spot size. Also available are options such as spectral locking and line narrowing, using Volume Bragg Gratings. (VBG)

Features

  • Industry standard size and footprint
  • High reliability and consistency
  • Hard solder available for harsh drive conditions
  • Low smile
  • Optional beam shaping
  • Optional spectral locking and line narrowing
  • Narrow heat sink variant available for side-by-side placement
  • Variants with different beam height on request

Applications

  • Pumping of solid-state lasers
  • Materials processing and annealing
  • Medical
  • Graphic arts
