Octave Spanning Ultrafast Laser Optics (400 – 500 nm Bandwidth)

  • The coatings shown here are calculated for a bandwidth of one octave in the range of the Ti:Sapphire laser (e.g. 550 – 1100 nm). Similar coatings are possible for other wavelength ranges.
  • Center wavelength, bandwidth, GDD and reflectance of output couplers and beam splitters according to customer specifications
  • Spectral tolerance ±1 %
  • In-house design calculation and GDD measurement capabilities
  • GDD measurement reports are included in the delivery

Negative Dispersion Laser Mirror Pairs for AOI = 0°

Mirror pairs designed by LAYERTEC show a very smooth average GDD spectrum even though the single broadband mirrors exhibit strong GDD oscillations.
