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.
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
- Commercial volume is delivering

PPLN Bulk Mixers
PPLN bulk mixer is made with PPLN bulk chips for various lasers from continuous wave (CW) to ultrafast pulse. Via different nonlinear wavelength conversion processes (e.g. SHG, SFG, DFG…etc), the PPLN bulk mixer provides the polarization maintained output from UV to mid-IR with output power up to few Watts either in free space or with optical fiber.
Key features
- Single-pass & high-efficiency, optimized for specified input pumps
- Output wavelength from UV/Visible to NIR/MIR
- Mixing configurations: SHG, SFG, DFG, Cascaded SHG-SFG (THG), Tunable, etc.
- 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)
- Integrated thermistor/Peltier (TEC) for QPM temperature optimization
- Photodiode (PD) for power monitoring/Automatic Power Control optional
- Convenient, compact and robust for application customizations
- Commercial volume is delivering

PPLN Cavity Mixers
Cavity configuration is an alternative way to enhance nonlinear frequency conversion. For your application convenience, we have developed cavity mixer platform which can be customized to a variety of mixer applications, such as external pump OPO (EP-OPO), Intra-cavity OPO (IC-OPO), intra-cavity SFG (IC-SFG), intra-cavity DFG (IC-DFG) etc. Example applications are for generating NIR signal wavelengths between 1.4-2 um and MIR idler wavelengths between 2.3-4.5 um.
Key features
- Cavity enhanced & high-efficiency, optimized for your specified input pump or desired output signal/idler
- Output wavelength from UV/Visible to NIR/MIR
- Mixing configurations from conventional type to advanced type (such as IC-OPO, IC-SFG, IC-SHG, IC-DFG, EP-OPO etc.)
- Fiber or free space as input/output coupling interfaces
- Integrated thermistor/TEC for QPM temperature optimization & optional photodiode (PD) for power monitoring/automatic power control
- Convenient, compact and robust
Example: IC-OPO
an ultra-low power consumed optical parametric oscillator (OPO)
The intracavity design of the OPO utilizes the high circulating power in the cavity to achieve extremely low threshold pump power.
ICOPO-B is fixed wavelength mixer specified by the customer in the range of either α, β or γ. ICOPO-TB is wavelength tunable mixer covers the entire range.
B: broad bandwidth, fixed wavelength (few nm)
T: tunable

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
