Harmonic Generator

Second-harmonic third-harmonic and fourth-harmonic accessory for Mira.

The Harmonic Generator is an extremely flexible and adaptable wavelength extension accessory for Coherent’s entire range of ultrafast oscillators (Mira, Chameleon, Vitara, Mira OPO, and Chameleon Compact OPO).

Second-, Third-, and Fourth-Harmonic Accessory for Ti:S Oscillators

A wide range of non-linear crystals and configuration options are available that span second, third and fourth harmonic generation of picosecond or femtosecond pulses at input powers up to 5W.

For third harmonic generation, the unique high efficiency collinear mixing design with walk-off compensation and inline time delay is simple to align without the complexity of separate optical delay lines and fundamental and SHG spatial separation and recombination. Key Advantages

  • Magnetically indexed crystals simplifies SHG/THG/FHG conversion
  • Walk-off compensator maintains good beam circularity
  • Delay compensator for simple inline THG generation
  • Easily upgradable
  • Autotracker option for SHG and THG. Provides automatic phase matching optimization as input wavelength is changed.
