Product Family Description

  • Separates Ultrafast Harmonic Wavelengths
  • Ultrafast Beamsplitter Coating with Low GDD
  • <λ/10 Wavefront Distortion
  • Designs for Ti:sapphire and Yb:doped Femtosecond Lasers

TECHSPEC® Ultrafast Harmonic Separators, also known as Ultrafast Harmonic Beamsplitters, are used to reflect the second or third harmonic of femtosecond lasers while transmitting the fundamental pulse. The reflective surface is designed to have high reflectivity and a low Group Delay Dispersion (GDD) of ±20fs2 to minimize pulse dispersion. The back surface is coated with an anti-reflection coating to enhance the transmission of the fundamental light. TECHSPEC Ultrafast Harmonic Separators provide low wavefront distortion and feature high quality, thin UV fused silica substrates with 10-5 surface quality. Designs for separating the harmonics of 800nm and 1030nm (Ti:sapphire and Yb:doped fiber) lasers are available.
