Overview
The NLK1B5EAAA is a high-stability distributed feedback (DFB) laser diode module engineered for precision gas sensing and spectroscopic analysis in the near-infrared (NIR) region. Based on monolithic DFB semiconductor architecture, it delivers single longitudinal mode (SLM) emission with narrow spectral linewidth (< 2 MHz typical), low relative intensity noise (RIN < −145 dB/Hz), and excellent wavelength stability over temperature and current variations. Its design leverages Bragg grating integration directly into the active waveguide layer, enabling intrinsic wavelength selectivity without external cavity components. This makes the NLK1B5EAAA particularly suitable for tunable diode laser absorption spectroscopy (TDLAS), where accurate targeting of molecular absorption lines—such as those of HF (1280–1340 nm), H2O (1320–1420 nm), NH3 (1490–1530 nm), CO (1540–1610 nm), H2S (1570–1620 nm), CH4 (1580–1670 nm), HCl (1735–1745 nm), and CO2 (1990–2010 nm)—is critical for quantitative trace-gas detection.

Sample Compatibility & Compliance
The NLK1B5EAAA is optimized for use in extractive and in-situ gas monitoring systems requiring high spectral fidelity and long-term repeatability. Its wavelength stability and low mode-hopping probability ensure consistent performance across industrial process control, environmental emissions monitoring (e.g., EPA Method 30B compliance), and laboratory-based TDLAS setups. The device meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. For regulated applications—including pharmaceutical cleanroom air quality verification or combustion exhaust analysis—the module supports integration into systems compliant with ISO 14644-1 (cleanroom classification), ASTM D6522 (gas chromatography–mass spectrometry reference method), and USP (validation of analytical procedures). Full traceable calibration data and MSA-compliant test reports are provided with each unit.
Software & Data Management
While the NLK1B5EAAA operates as a hardware component, it is fully compatible with industry-standard laser driver and controller platforms—including ILX Lightwave LDC-3724B, Wavelength Electronics QCL series drivers, and custom PID-controlled current/temperature modules. Its integrated thermistor and photodiode enable closed-loop stabilization via analog feedback or digital I²C/SPI interfaces (when paired with supporting electronics). When deployed in automated analyzers, the laser’s output can be synchronized with wavelength-scanning routines (e.g., 2f-wavelength modulation) and integrated into data acquisition frameworks adhering to IEEE 1451.2 transducer electronic data sheet (TEDS) conventions. Audit trails, configuration logs, and operational history may be maintained in accordance with FDA 21 CFR Part 11 requirements when embedded in validated GxP environments.
Applications
- Tunable diode laser absorption spectroscopy (TDLAS) for real-time, in-line measurement of HF, H2O, NH3, CO, CH4, and other NIR-absorbing gases
- Industrial process monitoring in semiconductor fabrication (etch gas purity), petrochemical refining (leak detection), and power generation (combustion efficiency)
- Environmental monitoring stations for ambient air quality assessment and fugitive emission quantification
- Research-grade optical frequency references and heterodyne detection systems
- Calibration sources for FTIR spectrometers and NIR photometers operating in the 1.28–1.67 µm window
FAQ
What is the typical spectral linewidth of the NLK1B5EAAA?
The intrinsic full width at half maximum (FWHM) linewidth is typically < 2 MHz under constant-current, constant-temperature operation.
Is wavelength tuning possible, and what is the tuning range?
Yes—via temperature tuning (≈0.1 nm/°C) and current tuning (≈0.01 nm/mA); total usable tuning span is ~0.5 nm within the specified band, sufficient for scanning across individual molecular absorption features.
Does the module include built-in monitoring and control circuitry?
No—the NLK1B5EAAA is a bare laser module requiring external laser diode driver and TEC controller. However, all necessary monitor signals (photodiode current, thermistor resistance) are accessible via dedicated pins per MIL-STD-704 pinout.
Can this laser be integrated into an OEM gas analyzer system?
Yes—it is widely deployed in OEM configurations. Mechanical drawings, thermal management guidelines, and EMI/EMC test summaries are supplied to support mechanical, thermal, and regulatory integration.
What documentation accompanies the unit?
Each shipment includes a Certificate of Conformance (CoC), detailed electrical/optical test report (including L-I-V curves, SMSR, and wavelength vs. temperature data), RoHS/REACH declaration, and handling instructions compliant with JESD22-A108 moisture sensitivity level (MSL) 1.
