  • PPLN Waveguide Mixers: super efficient frequency converter

    PPLN waveguide mixers are frequency conversion modules which integrate PPLN waveguide chips into a convenient, compact, robust, cost-effective packaged format for your application convenience. With waveguide structure, PPLN waveguide mixers have higher efficiency in single-pass configuration as compared to bulk mixers. Optimized for your desired input pump lasers, PPLN waveguide mixers provide the polarization maintained output either in free space or optical fiber, with available output wavelength ranging from UV/Visible to NIR/MIR and output power up to sub-Watt or even up to Watt level.

    Please check the details with "Reference specifications -4W" below.

    Key features

    • Single-pass & high-efficiency, optimized for specified input pumps
    • Output wavelength from UV/Visible to NIR/MIR
    • Mixing configurations: SHG, SFG, DFG, etc.)
    • Fiber or free space as input/output coupling interfaces (such as 1x0, 1x1, 2x0, 2x1, 0x0; 0=free space (collimated beam optional), 1=one fiber, 2=dual fibers
    • Integrated thermistor/Peltier (TEC) for QPM temperature optimization 
    • Photodiode (PD) for power monitoring/Automatic Power Control optional
    • Convenient, compact and robust for application customizations

  • PPLN Pulse Mixers

    PPLN under pulse operation (ns/ps/fs) can be classified in a special category due to its unique features. Under high peak power operation, conversion efficiency in general could be relatively higher and could even enable OPA/OPG applications. However. crystal damage, pulse spectrum, and temporal walk-off effect in general needs to be taken into special consideration. We have developed several pulse bulk/waveguide mixers with optimization of above special pulse conditions.

    Key features

    • Pump by ns-Q switch laser or ps/fs ultrafast laser, with spectrum, temporal walk-of and damage optimization.
    • Available output wavelength from UV/Visible to NIR/MIR 
    • Available mixing configuration from fundamental type to advanced type     (such as SHG/SFG/DFG, or OPA/OPG etc.)
    • Available for fiber or free space as input/output coupling interfaces      (such as 1x0, 1x1, 2x0, 2x1, 0x0 , 0=free space, 1=one fiber, 2=dual fibers, with optional alignment beam for free space input) 
    • Available with integrated thermistor/TEC for QPM temperature optimization & optional photodiode (PD) for power monitoring/automatic power control
    • Convenient, compact and robust and available for a variety of application customizations
