Overview
The RealLight AQE Series is a high-energy, diode-pumped, actively Q-switched solid-state (DPSS) laser system engineered for precision pulsed laser applications requiring robust single-pulse energy, temporal stability, and compact integration. Based on a proprietary GS-series semiconductor stack pump source and monolithic resonator architecture, the AQE Series delivers ≥50 mJ at 1064 nm and ≥30 mJ at 532 nm with sub-6 ns pulse width and RMS power stability better than 3%. Its fully integrated laser head and driver design—combined with conductive thermal management and air-cooling—enables reliable operation in space-constrained environments without external chillers or water lines. The system complies with IEC 60825-1:2014 for Class 4 laser safety and is optimized for applications demanding high peak power density, including laser-induced breakdown spectroscopy (LIBS), laser ablation for material processing and thin-film deposition, optical damage threshold characterization, and time-resolved photoluminescence excitation.
Key Features
- High Pulse Energy Output: Delivers ≥50 mJ at fundamental 1064 nm and ≥30 mJ at frequency-doubled 532 nm—engineered for efficient plasma generation and ablation threshold studies.
- Actively Q-Switched Architecture: Utilizes electro-optic or acousto-optic modulation synchronized with the GS-series high-brightness diode stack to ensure precise temporal control and low jitter (<5 ns).
- Compact Monolithic Design: Integrated laser head and controller (75 × 60 × 130 mm) minimizes footprint and simplifies OEM integration into vacuum chambers, LIBS spectrometers, or ablation cells.
- Air-Cooled Thermal Management: Passive conduction combined with forced-air cooling eliminates dependency on recirculating chillers—reducing total cost of ownership and improving field deployment flexibility.
- Industrial-Grade Control Interface: J30J-15ZKL military-spec connector supports TTL-compatible internal/external triggering, analog monitoring outputs (pulse energy, temperature), and RS-232 or optional USB communication for remote parameter adjustment.
- Stable Beam Profile & Low Divergence: Near-diffraction-limited output with full-angle divergence of ≤2 mrad (1/e²) in both horizontal and vertical axes ensures consistent focusability and energy density across target surfaces.
Sample Compatibility & Compliance
The AQE Series is compatible with standard optical tables, motorized translation stages, and vacuum-compatible ablation chambers (up to 10⁻⁵ mbar). Its 1064 nm and 532 nm wavelengths enable broad material interaction—from wide-bandgap dielectrics (e.g., fused silica, CaF₂) to metals (Cu, Al, Ti) and biological tissues—supporting quantitative ablation rate calibration and stoichiometric transfer analysis. All units are CE-marked and conform to IEC 60825-1:2014 (Class 4) laser safety standards. For regulated environments—including GLP-compliant analytical labs or ISO/IEC 17025-accredited testing facilities—the system supports audit-ready operation logs when paired with compliant data acquisition software (see Software & Data Management).
Software & Data Management
RealLight provides the AQE Control Suite—a Windows-based application supporting real-time pulse energy monitoring, repetition rate programming, trigger delay calibration, and thermal status logging. The software exports timestamped CSV datasets with metadata (pulse number, energy reading, head temperature, interlock status) for traceability. When deployed in FDA-regulated settings (e.g., medical device ablation validation), the suite can be configured to comply with 21 CFR Part 11 requirements—including electronic signatures, audit trails, and role-based access control—via optional GxP add-on modules. Raw data streams are accessible via ASCII protocol over RS-232 or USB CDC, enabling seamless integration with LabVIEW, Python (PySerial), or MATLAB-based custom analysis pipelines.
Applications
- Laser-Induced Breakdown Spectroscopy (LIBS): Stable ≥50 mJ pulses generate reproducible microplasmas with high signal-to-background ratio for elemental quantification in soils, alloys, and geological samples.
- Laser Ablation ICP-MS/OES: Enables uniform crater morphology and minimal fractionation in conductive/non-conductive solids—validated for NIST SRM 610 glass and USGS basalt standards.
- Optical Damage Threshold Testing: Precise pulse energy control and beam homogeneity support ISO 21254-compliant LIDT measurements on coatings, crystals, and AR/HR mirrors.
- Time-Resolved Photoluminescence (TRPL): Sub-6 ns pulses serve as excitation sources for carrier lifetime analysis in perovskites, GaN, and quantum dot films.
- Micromachining & Thin-Film Patterning: Compatible with galvo scanners and f-theta lenses for direct-write ablation of polymers, oxides, and 2D materials at kHz-scale burst modes (via external sync).
FAQ
Is the AQE Series suitable for vacuum chamber integration?
Yes—its sealed, conduction-cooled laser head and absence of outgassing components (e.g., no silicone seals or lubricants) permit operation in high-vacuum environments up to 10⁻⁵ mbar.
Can pulse energy be adjusted dynamically during operation?
Pulse energy is fixed per wavelength channel but can be attenuated externally using calibrated reflective neutral density filters; internal energy scaling is not supported to preserve beam quality and stability.
What safety interlocks are included?
Standard interlocks include temperature cutoff (>45 °C), power supply overvoltage protection, and external key switch interface compliant with EN 61508 SIL2 requirements.
Does RealLight provide OEM customization options?
Yes—options include custom pulse repetition rates (5–20 Hz), harmonic generation modules (266 nm, 213 nm), fiber-coupled output, and mechanical housing modifications for embedded integration.
How is calibration traceability maintained?
Each unit ships with a NIST-traceable calibration certificate for pulse energy (measured with Ophir PE50BF-SH-V1 sensor) and beam divergence (verified via scanning slit profiler), valid for 12 months under normal operating conditions.
