Harmonic Separators

Harmonic Separators

  • Designed to separate YAG laser outputs as a function of wavelength
  • Three standard designs provide alternate transmission/reflection of the harmonics
  • Measured laser damage threshold guidelines
  • Provided on Grade A BK7 substrates
  • Surfaces finished to λ/10 flatness
  •   Available for 532/1064 and 355/1064

 

These are dichroic (i.e., color dependent) beamsplitters which separate the YAG fundamental from its second harmonic. Three configurations are offered. One reflects the fundamental and the second reflects the 532nm harmonic and the third reflects the 355nm harmonic. They are available in four sizes 25.4mm, 30mm, 50mm and 50.8mm diameter.
