Auniontech AUT-CI-QBHM2 Series QBH-Interface High-Power Laser Beam Propagation Analyzer (M² Measurement System)

Overview

The Auniontech AUT-CI-QBHM2 Series is a purpose-engineered, integrated beam propagation analyzer designed for direct, traceable measurement of laser beam quality parameters from high-power QBH-terminated fiber lasers. Operating on the principles defined in ISO 11146-1 and ISO 11146-2, the system implements the variable-aperture (knife-edge or scanning-slit) or ISO-compliant camera-based iterative beam-waist scanning method to determine the beam propagation ratio (M²), beam parameter product (BPP), Rayleigh length, divergence angle, beam waist diameter, and spatial intensity distribution (2D/3D). Unlike conventional free-space M² systems requiring complex alignment and attenuation, the AUT-CI-QBHM2 features a monolithic QBH-compatible mechanical interface that enables direct coupling of industrial-grade fiber lasers—eliminating optical realignment, minimizing thermal lensing artifacts, and preserving beam fidelity under sustained high-power operation up to 20 kW.

Key Features

• QBH-standard mechanical interface with integrated water-cooled heat sink and thermal management architecture for continuous-wave (CW) and quasi-CW laser sources
• Optimized optical path design with calibrated neutral-density filtering and beam-splitting optics compliant with ISO 11146 measurement geometry
• CinCam series high-dynamic-range CMOS beam profiler with pixel-level linearity correction and temperature-stabilized sensor housing
• RayCi-Pro v5.x software suite supporting automated ISO 11146-compliant M² calculation, real-time beam centroid tracking, and statistical stability analysis (e.g., RMS position drift over time)
• Compact, benchtop-integrated enclosure with EMI-shielded electronics, CE-marked power supply, and interlocked safety shutter per IEC 60825-1
• Pre-calibrated factory alignment; no user optical adjustment required—“power-on, connect, measure” operational workflow

Sample Compatibility & Compliance

The AUT-CI-QBHM2 is engineered exclusively for QBH-terminated single-mode and multimode fiber laser outputs operating within 400–1150 nm. It supports both CW and pulsed (≥100 ns pulse width, ≥1 kHz repetition rate) sources meeting ANSI Z136.1 Class 4 laser safety requirements. All optical components—including fused silica imaging lenses, reflective beam dumps, and thermally compensated sensor mounts—are qualified for >10⁷ shot cycles at rated power. The system conforms to ISO 11146-1:2021 (determination of beam widths, divergence, and M²) and ISO 11146-2:2021 (test methods for directional beam parameters), and includes full calibration documentation traceable to NIM (National Institute of Metrology, China). Optional GLP/GMP audit trail logging and FDA 21 CFR Part 11-compliant electronic signatures are available via RayCi-Pro Enterprise license.

Software & Data Management

RayCi-Pro v5.x provides a deterministic, standards-aligned computational engine for beam characterization. It implements dual-path M² computation: (i) the ISO-recommended iterative scan method across ≥10 axial positions with sub-micron stage resolution, and (ii) a fast-fit Gaussian decomposition algorithm for rapid diagnostics. Raw image data is stored in HDF5 format with embedded metadata (timestamp, power reading, ambient temperature, stage position). The software supports automated report generation in PDF/CSV formats compliant with internal QA protocols, including pass/fail thresholds for M² deviation from specification limits. Network-enabled remote monitoring, API access (RESTful JSON interface), and integration with LabVIEW™ and MATLAB® toolchains are standard. Audit logs record all user actions, parameter changes, and calibration events with immutable timestamps.

Applications

This system is deployed in laser source manufacturing facilities for final QC validation of QBH-fiber lasers used in sheet metal cutting, thick-plate welding, and additive manufacturing. It serves as a reference metrology tool in national metrology institutes validating high-power laser radiometry chains. In R&D environments, it supports development of novel fiber architectures (e.g., photonic crystal fibers, tapered fiber bundles) where modal content and near-field/far-field coupling must be quantified under realistic thermal load conditions. End users include Tier-1 OEMs in automotive and aerospace sectors requiring full traceability of beam quality metrics per AS9100D and IATF 16949 process audits.

FAQ

What laser power levels can the AUT-CI-QBHM2 safely measure?
It is rated for continuous operation up to 20,000 W (20 kW) at 1070 nm with active water cooling. Power derating applies outside the 400–1150 nm band per optical coating specifications.
Does the system require external beam attenuation?
No—its integrated ND filter stack and reflective beam dump architecture are pre-optimized for direct QBH coupling without user-installed attenuators.
Is RayCi-Pro software validated for regulated environments?
Yes—optional 21 CFR Part 11 modules provide electronic signature enforcement, role-based access control, and tamper-evident audit trails.
Can the system measure M² for non-Gaussian or multimode beams?
Yes—RayCi-Pro implements second-moment (ISO) and D4σ algorithms, enabling accurate M² determination for arbitrary intensity profiles including top-hat, donut, and super-Gaussian distributions.
What calibration services are available post-purchase?
Auniontech offers annual on-site recalibration with NIM-traceable certificates, including beam width uncertainty budgeting per GUM (JCGM 100:2008).
