Overview
The A10767 QCL Thermal Guide is a precision-engineered optical subassembly designed for stable thermal management and beam conditioning of mid-infrared quantum cascade lasers (QCLs). Developed by Hamamatsu Photonics K.K. in Japan, this component serves as a critical interface between the QCL chip and downstream optical systems—enabling consistent thermal dissipation, mechanical alignment stability, and low-optical-loss coupling into free-space or fiber-coupled configurations. Unlike generic heat sinks or passive mounts, the A10767 integrates a thermally optimized copper-tungsten baseplate with micro-machined alignment features and integrated temperature-sensing pathways compatible with closed-loop thermo-electric cooler (TEC) control circuits. Its design adheres to industry-standard mounting footprints for 7.5 mm × 7.5 mm QCL packages and supports continuous-wave (CW) and pulsed operation modes across spectral ranges from 4.0 µm to 12.0 µm. The device does not function as a standalone instrument but operates exclusively as an OEM-grade subsystem within larger laser-based analytical platforms—such as gas-phase spectroscopic analyzers, environmental monitoring sensors, and industrial process control systems requiring trace-gas detection.
Key Features
- Thermally matched CuW (copper–tungsten) baseplate with coefficient of thermal expansion (CTE) engineered to minimize stress-induced wavelength drift in mounted QCL chips
- Precision-machined kinematic alignment grooves and fiducial marks for repeatable, sub-5 µm positional reproducibility during optical bench integration
- Integrated Pt1000 temperature sensor port compatible with standard 4-wire RTD readout circuits for real-time thermal feedback
- Optimized thermal interface geometry supporting both conductive cooling (via cold plate) and active TEC integration (up to 6 W cooling capacity)
- RoHS-compliant construction with gold-plated copper contacts and vacuum-compatible materials (outgassing rate <1×10⁻⁹ Pa·m³/s per ASTM E595)
- Designed for compatibility with Hamamatsu’s A10765 series QCL modules and third-party QCL emitters conforming to JEDEC MO-252 package standards
Sample Compatibility & Compliance
The A10767 is intended for integration with quantum cascade laser sources emitting in the mid-infrared (MIR) spectrum. It accommodates standard TO-66, HHL, and butterfly-style QCL packages with thermal load requirements up to 8 W under CW operation. Mechanical compatibility extends to optical breadboards utilizing M3 and M4 mounting threads, and its footprint aligns with common laser diode mount adapters (e.g., Thorlabs LDM9LP, Newport 98000 series). From a regulatory perspective, the unit complies with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity requirements) when installed within shielded host systems. As an OEM component—not a finished medical or safety-certified device—it carries no CE marking or FDA 510(k) clearance; however, its material certifications (including ISO 9001:2015 manufacturing traceability and JIS Z 3197 solderability validation) support qualification under ISO 13485 and AS9100 frameworks where applicable.
Software & Data Management
The A10767 itself contains no embedded firmware or digital interfaces. Thermal performance data acquisition and control are managed externally via host system architecture. When integrated into automated platforms, users typically interface the integrated Pt1000 sensor and TEC driver lines through industrial analog I/O modules (e.g., National Instruments PXIe-6363 or Keysight 34972A) or custom FPGA-based controllers. Hamamatsu provides reference schematics and thermal modeling files (ANSYS Fluent-ready geometry and boundary condition templates) to facilitate system-level thermal simulation and PID loop tuning. All calibration documentation—including thermal resistance curves (Rth,j-c vs. mounting torque), sensor linearity reports (±0.15 °C accuracy over −10 °C to +70 °C), and mechanical runout specifications—is delivered with each production lot in accordance with ISO/IEC 17025-accredited test records.
Applications
- Trace gas analysis systems employing tunable QCL absorption spectroscopy (TDLAS) for ppm-level detection of CO, NOx, CH4, NH3, and volatile organic compounds (VOCs)
- Portable and airborne environmental monitoring payloads requiring high thermal stability across ambient temperature swings (−20 °C to +55 °C)
- Industrial combustion optimization sensors deployed in boiler flue gas streams and semiconductor fab exhaust lines
- Research-grade MIR optical parametric oscillators (OPOs) and difference-frequency generation (DFG) pump stages demanding precise QCL wavelength locking
- Calibration transfer standards for FTIR spectrometers operating in the 1000–2500 cm⁻¹ wavenumber range
FAQ
Is the A10767 suitable for cryogenic operation?
No. The A10767 is rated for operational temperatures from −10 °C to +70 °C at the baseplate. Cryogenic use may induce interfacial delamination due to CTE mismatch and is not validated.
Does Hamamatsu provide driver electronics for the integrated TEC?
No. The A10767 includes only the thermal guide assembly and sensor interface. Users must supply external TEC drivers meeting current compliance (±0.5% setpoint stability) and noise specifications (<100 µA RMS ripple).
Can the A10767 be reflow soldered?
No. Reflow is incompatible with the internal sensor wiring and epoxy-bonded optical elements. Manual soldering using localized hot air (≤350 °C for <10 s) is permitted only on designated contact pads.
What documentation accompanies shipment?
Each unit ships with a Certificate of Conformance (CoC), thermal test report (per lot), mechanical drawing (PDF + STEP), and RoHS/REACH declaration. NDA-restricted optical characterization data is available upon request for qualified OEM partners.
