Overview
The RAYSCIENCE COPO Series is a turnkey, benchtop mid-infrared (MIR) optical parametric oscillator (OPO) system engineered for precision wavelength selection and stable pulsed output across the molecular fingerprint region. Operating on the principle of nonlinear frequency conversion in periodically poled magnesium oxide–doped lithium niobate (MgO:PPLN), the COPO system enables coherent, tunable MIR generation via difference-frequency mixing between pump and signal waves inside a quasi-phase-matched crystal cavity. With a continuous tuning range spanning 1390–4200 nm (7200–2350 cm⁻¹), it delivers spectrally resolved illumination critical for absorption spectroscopy, gas sensing, and infrared component validation. Unlike free-space OPO setups requiring manual alignment and phase-matching recalibration, the COPO integrates a diode-pumped solid-state (DPSS) 1064 nm or 1047 nm pump laser, thermal stabilization, and real-time crystal temperature control — enabling push-button wavelength selection with ≤1 nm step resolution and sub-5 pm spectral linewidth.
Key Features
- Turnkey operation: Fully assembled, pre-aligned, and factory-optimized for immediate deployment in laboratory or industrial test environments
- Wide spectral coverage: Continuous tuning from 1390 nm to 4200 nm — encompassing key atmospheric transmission windows (e.g., 3–5 µm and 8–12 µm bands) and fundamental vibrational transitions of hydrocarbons, NOₓ, CO₂, CH₄, and H₂O
- Dual-output configuration: Simultaneous access to signal (20–50 mW) and idler (5–25 mW) beams via integrated motorized filter wheel; user-selectable output path for unfiltered OPO/pump light
- Pulsed temporal profile: ~15 ns pulse width at ~2 kHz repetition rate (customizable to 1–10 kHz upon specification); compatible with time-resolved detection and gated acquisition protocols
- Intuitive human-machine interface: Touch-enabled front panel with wavelength entry keypad, preset recall, and real-time status feedback (crystal temperature, pump power, OPO lock status)
- Robust thermal architecture: Active cooling of MgO:PPLN crystal and pump diode ensures long-term wavelength stability (< ±0.5 nm over 8 h) and repeatability under ambient lab conditions (20–25 °C)
Sample Compatibility & Compliance
The COPO system is designed for non-contact, non-destructive interrogation of gaseous, liquid, and solid-phase samples in transmission, reflection, or photoacoustic configurations. Its output is compatible with standard IR optics (ZnSe, CaF₂, Ge, KBr windows), FTIR spectrometers (Bruker, Thermo Fisher), mercury cadmium telluride (MCT) detectors, and InSb focal plane arrays. The system meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and laser safety (IEC 60825-1:2014 Class IV). While not certified for medical device use per FDA 21 CFR Part 820, its traceable wavelength calibration (NIST-traceable reference lines available upon request) supports GLP-compliant spectroscopic method development in environmental monitoring and materials QA/QC labs.
Software & Data Management
The COPO includes RAYSCIENCE’s proprietary OPOControl v3.2 software suite, supporting Windows 10/11 (64-bit) and offering USB 2.0 or Ethernet communication. Functions include remote wavelength scanning with linear/logarithmic step modes, automated spectral mapping, power stabilization loops (±2% RMS), and export of timestamped .csv datasets containing wavelength, output power, crystal temperature, and pump energy. Audit trails record all parameter changes with user ID and UTC timestamps — satisfying basic 21 CFR Part 11 data integrity requirements when deployed with validated IT infrastructure. Third-party integration is enabled via TCP/IP socket commands and LabVIEW-compatible DLLs.
Applications
- High-resolution absorption spectroscopy of greenhouse gases and trace pollutants (e.g., NH₃ at 3020 cm⁻¹, HF at 3962 cm⁻¹)
- Calibration source for infrared imaging systems, thermal cameras, and uncooled microbolometer arrays
- Characterization of anti-reflection coatings, dichroic filters, and waveguide dispersion in chalcogenide glass platforms
- Photoacoustic spectroscopy (PAS) excitation in trace explosive vapor detection and breath analysis
- Nonlinear optics education and research: degenerate/non-degenerate OPO dynamics, cavity dumping, and pump depletion studies
- Free-space optical communications testing in the L-band (1565–1625 nm) and U-band (1625–1675 nm) windows
FAQ
What is the typical beam quality (M²) of the COPO output?
The signal beam exhibits M² < 1.3 (TEM₀₀) at 1550 nm; idler beam M² ranges from 1.4–1.7 depending on wavelength and crystal orientation.
Can the COPO be synchronized with external equipment?
Yes — TTL-compatible sync outputs are provided for pump trigger, Q-switch, and OPO cavity dump timing with jitter < 5 ns.
Is vacuum or purged operation required for long-wavelength output (>3500 nm)?
No — the system operates reliably in ambient air; however, for applications demanding minimal H₂O/CO₂ absorption above 3000 nm, optional N₂ purge ports are available.
Does the system support custom wavelength presets for routine measurements?
Yes — up to 128 user-defined wavelengths can be stored and recalled via front panel or software with associated power optimization profiles.
What maintenance is required during normal operation?
No routine optical alignment or crystal replacement is needed; annual verification of pump diode output power and thermal sensor calibration is recommended.
