ZOLIX ZL-OPA Series Optical Parametric Amplifier

Overview

The ZOLIX ZL-OPA Series Optical Parametric Amplifier is a high-performance, pump-laser-agnostic ultrafast light source engineered for broadband tunability and exceptional temporal fidelity. Based on collinear optical parametric amplification in nonlinear β-barium borate (BBO) and potassium titanyl phosphate (KTP) crystals, the system leverages difference-frequency generation (DFG) and second-harmonic generation (SHG) to deliver coherent, femtosecond-scale pulses across an extended spectral range—from deep ultraviolet (200 nm, via harmonic upconversion) through visible and near-infrared to mid-infrared (up to 10 µm). Designed for integration with industry-standard Yb-doped fiber or solid-state amplifiers operating at repetition rates from single-shot to 100 kHz, the ZL-OPA series provides deterministic wavelength selection with precise angular and temperature tuning of nonlinear crystals. Its monolithic optomechanical architecture ensures long-term alignment stability and minimal thermal drift—critical for time-resolved spectroscopy, ultrafast pump-probe experiments, and coherent control applications requiring sub-100-fs pulse integrity.

Key Features

• Two optimized configurations: ZL-OPA-HP (high-power, <500 fs output) and ZL-OPA-HE (high-efficiency, <100 fs output), each with distinct signal/idler tuning ranges and pulse duration profiles
• Wide pump acceptance window: compatible with 10 µJ–2 mJ, 35 fs–1.5 ps Yb-based pump sources—enabling seamless integration with commercial regenerative amplifiers and high-repetition-rate fiber systems
• Robust mechanical design featuring kinematic crystal mounts, motorized rotation stages, and vacuum-compatible housing options for reduced air dispersion and thermal noise
• Integrated beam diagnostics: real-time monitoring of output energy, spatial mode profile, and polarization state via optional calibrated photodiodes and imaging sensors
• Modular extension capability: standardized interfaces support add-on modules for UV generation (325–515 nm), green output (515–650 nm), and mid-IR detection pathways
• Long-term power stability better than 1% RMS over 8 hours at 750 nm—validated under continuous operation in ambient laboratory conditions without active cooling

Sample Compatibility & Compliance

The ZL-OPA series is designed for use in research-grade ultrafast laboratories where reproducibility and regulatory traceability are essential. While not classified as a medical or industrial process instrument, its optical performance adheres to foundational metrological principles outlined in ISO 11146 (laser beam parameters) and ISO 13694 (laser-induced damage threshold testing). All nonlinear crystals are certified for laser-induced damage threshold (LIDT) >500 mJ/cm² at 1030 nm, 100 fs (tested per ISO 21254-2). The system supports GLP-compliant experimental workflows through stable output calibration and repeatable tuning protocols. Optional NIST-traceable energy calibration kits enable users to maintain measurement consistency across multi-user facilities and inter-laboratory studies.

Software & Data Management

Control is executed via ZOLIX’s proprietary OPA Control Suite—a cross-platform application (Windows/Linux) providing intuitive GUI-driven tuning, automated wavelength scanning, and real-time pulse characterization. The software implements bidirectional communication with motorized stages and energy meters using standard USB 2.0 and RS-232 interfaces. All operational parameters—including crystal angles, pump energy, repetition rate, and output wavelength—are logged with timestamped metadata in HDF5 format, ensuring full auditability. Export functions support MATLAB, Python (NumPy), and Igor Pro native data structures. For regulated environments, optional FDA 21 CFR Part 11 compliance packages include electronic signatures, role-based access control, and immutable audit trails for all tuning and calibration events.

Applications

• Ultrafast transient absorption spectroscopy spanning UV–MIR spectral domains
• Cohérent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS) microscopy with tunable excitation
• Time-resolved photoemission spectroscopy (TR-PES) requiring high-flux, narrow-bandwidth UV pulses
• Molecular fingerprinting in gas-phase reaction dynamics using dual-comb OPA seeding
• Mid-IR pump-probe studies of phonon dynamics in quantum materials and 2D heterostructures
• Seed source for high-energy OPCPA systems targeting petawatt-class laser facilities

FAQ

What pump lasers are compatible with the ZL-OPA series?

The system accepts Yb-doped fiber or solid-state ultrafast amplifiers delivering 35 fs–1.5 ps pulses at energies between 10 µJ and 2 mJ, with central wavelengths near 1030 nm.
Can the ZL-OPA generate sub-200 nm output?

Yes—via third-harmonic generation (THG) of the signal beam in BBO or KBBF crystals; custom UV extension modules are available upon request.
Is remote operation supported?

Yes—OPA Control Suite includes TCP/IP server mode for integration into automated experiment control frameworks (e.g., EPICS, LabVIEW, Python-based orchestration tools).
What maintenance is required for long-term stability?

No routine optical realignment is needed; periodic verification of crystal angle zero-points and energy meter calibration (annually recommended) ensures continued specification compliance.
Are OEM integration services available?

ZOLIX offers full OEM engineering support—including mechanical footprint adaptation, electrical interface redesign, and firmware-level API development—for turnkey integration into larger laser systems.
