Overview
The ICOPO Mixer by Longcai Technology (HCP) is a precision-engineered, cavity-enhanced optical mixing module designed for advanced infrared spectroscopy and nonlinear frequency conversion applications. Operating on the principle of intracavity difference-frequency generation (DFG) or sum-frequency mixing within a stable, thermally controlled resonant cavity, the module enables high-efficiency spectral translation across two strategically defined infrared bands: 1.4–1.9 µm (near-infrared, NIR) and 2.4–4.4 µm (mid-infrared, MIR). Its core architecture integrates a low-loss, high-finesse optical cavity with optimized nonlinear crystal orientation and pump beam management—enabling enhanced conversion efficiency without requiring ultra-high peak-power lasers. The device is engineered for laboratory-based IR source development, trace gas sensing calibration, and dual-band photonic instrumentation where simultaneous or switchable NIR/MIR output is critical.
Key Features
- Cavity-enhanced mixing architecture delivering improved conversion efficiency over free-space DFG configurations
- Dual-output capability: independent, collinear or spatially separated NIR (1.4–1.9 µm) and MIR (2.4–4.4 µm) beams
- Configurable spectral bandwidth: selectable broadband (B) mode for spectroscopic scanning or narrowband (S) mode for high-resolution line tuning
- Flexible interface options: free-space beam delivery (with kinematic mounts and AR-coated input/output windows) or fiber-coupled variants (FC/APC or SMA-905, compatible with SMF-28 or ZBLAN fibers)
- Thermally stabilized cavity housing with integrated temperature sensors and PID-controlled thermal management (±0.05 °C stability)
- Modular mechanical design compliant with standard 30 mm cage system and Ø1″ post-mounting interfaces
Sample Compatibility & Compliance
The ICOPO Mixer is intended for integration into OEM spectroscopic platforms and research-grade IR systems. It supports common pump sources including tunable OPOs, fiber lasers (e.g., Tm/Ho-doped), and quantum cascade laser (QCL) arrays operating within specified pump wavelength and power ranges (typically 1–2 W CW or 99.95% reflectivity in designated bands with <0.1 ppm absorption loss. The module complies with CE marking requirements for electromagnetic compatibility (EN 61326-1) and safety (EN 61010-1). While not certified for medical or industrial process control use out-of-the-box, it supports traceability documentation and can be qualified per customer-specific GLP/GMP protocols when integrated into validated analytical systems.
Software & Data Management
The ICOPO Mixer operates as a hardware-integrated optical component rather than a standalone instrument with embedded firmware. Control of external pump lasers, cavity alignment actuators (where equipped), and thermal setpoints is managed via host system software using standard communication interfaces: USB 2.0 (CDC/ACM class), RS-232, or optional Ethernet (TCP/IP). Longcai provides LabVIEW™ VI libraries and Python API wrappers (via PySerial or PyVISA) for automated wavelength sweeping, cavity lock acquisition, and real-time power monitoring. All operational parameters—including cavity temperature, incident pump power, and output port selection—are logged with timestamped metadata in CSV or HDF5 format, supporting audit-ready data integrity in regulated environments aligned with FDA 21 CFR Part 11 principles (when deployed with appropriate system-level electronic signature and audit trail implementation).
Applications
- High-sensitivity photoacoustic or cavity ring-down spectroscopy (CRDS) systems requiring simultaneous dual-band excitation
- Calibration source development for FTIR spectrometers and portable MIR gas analyzers targeting CO, CH₄, N₂O, and VOCs
- Nonlinear optical studies involving phase-matching optimization in orientation-patterned GaAs (OP-GaAs) or PPLN crystals
- Multi-spectral imaging testbeds where synchronized NIR reflectance and MIR absorption contrast are required
- Quantum optics experiments leveraging entangled photon pair generation via cavity-enhanced SPDC in tailored waveguide structures
FAQ
Is the ICOPO Mixer compatible with femtosecond laser pumps?
Yes—when configured with dispersion-compensated cavity design and appropriate crystal poling period, it supports sub-100 fs Ti:Sapphire or Yb-fiber pump sources under custom order.
Can I switch between NIR-only and MIR-only output modes?
Yes—the module includes internal dichroic steering optics enabling user-selectable single-band output or simultaneous dual-band operation via manual or motorized filter wheel integration.
Does Longcai provide cavity alignment support?
Yes—each unit ships with alignment verification report, cavity finesse measurement data, and remote technical support for initial cavity locking procedures using HeNe or diode reference lasers.
What is the typical warm-up time to thermal equilibrium?
Under ambient lab conditions (23 ± 2 °C), full thermal stabilization is achieved within 15 minutes after power-on, verified by internal thermistor readout and output power drift <0.3% over 1 hour.
Are OEM integration kits available?
Yes—Longcai offers mechanical mounting brackets, fiber coupling adapters, vacuum-compatible versions (up to 10⁻⁶ mbar), and custom coating options for specific laser line rejection or transmission requirements.
