Coherent Mira OPO Optical Parametric Oscillator

Synchronously-pumped OPO's for the Mira-900 and Mira-HP oscillators


The Mira-OPO is available in four different OPO crystal formats; Periodically Poled KTP, Fan-Poled KTP, Bulk KTP and Bulk CTA. The choice of bulk or periodically-poled crystal technology lets users select the best solution based on tuning - ease of use and performance, for their specific application. For maximum flexibility, any version of the Mira-OPO can be upgraded to any other version.


PP-Automatic, Fan-Poled and Bulk Crystal configurations are available in a linear or ring-cavity design. The linear-cavity design is the best solution for maximum power at IR Signal and Idler wavelengths. The ring cavity Mira-OPO is the preferred choice for applications requiring high power in the visible range. The ring-cavity design with intracavity second harmonic generation (SHG) takes advantage of the high intracavity power to efficiently generate visible output from 500 nm to 700 nm, which fills the gap between the fundamental output and the SHG output of a modelocked Ti:Sapphire oscillator. All versions of the ring-cavity configuration also include optics that cover infrared operation.


Overall, Mira-OPOs provide the industry’s most unique range of wavelength coverage in the infrared through the visible spectrum and are available in femtosecond, picosecond or long-picosecond configurations.



  • Unique fan-poled crystal technology for independent tunability of pump and OPO wavelengths
  • IR and visible/IR versions
  • Simple, fast wavelength tuning
  • Low pump threshold: As low as 0.5W
  • High power visible output using highly efficient intracavity doubling
  • Access to idler wavelengths to ~4μm using optional optics sets
  • Active cavity length stabilisation on all models
  • Active pulse width or bandwidth stabilisation (optional for Bulk Crystal version)
  • Options availbale include: fs and ps crystal options, short pulse configurations (sub-100fs and sub-50fs), DFG option extends wavelength to 15µm
