Innolume BAD1320010CM003WXXXX High-Power Broad-Area Laser Diode

Overview

The Innolume BAD1320010CM003WXXXX is a single-emitter, broad-area laser diode engineered for high-brightness continuous-wave (CW) operation at the technologically critical 1320 nm wavelength. Designed using Innolume’s proprietary quantum-well active region and monolithically integrated waveguide architecture, this device delivers 2 W of optical output power under optimized thermal management—making it suitable for demanding applications in biomedical imaging, fiber-optic sensing, and pump sources for optical parametric oscillators (OPOs). Unlike multi-mode fiber-coupled modules, this open-heat-sink C-mount device provides direct access to the laser chip for integration into custom optomechanical platforms. Its emission is invisible near-infrared radiation (NIR), classified as Class 4 laser product per IEC 60825-1:2014, requiring strict adherence to laser safety protocols during handling and system integration.

Key Features

• 2 W CW output power at 1320 nm with high spatial coherence and low beam divergence (typ. < 10° vertical, < 6° horizontal FWHM)
• Proprietary facet passivation and mirror coating technology ensuring >10,000 hours MTTF under rated operating conditions
• Au/Sn eutectic bonding between laser chip and copper-tungsten composite submount for superior thermal impedance (< 0.3 K/W junction-to-baseplate)
• RoHS-compliant materials and manufacturing processes aligned with EU Directive 2011/65/EU
• C-mount mechanical interface compatible with industry-standard heatsinks and thermal test fixtures
• Integrated back-facet monitor photodiode (optional configuration available upon request)

Sample Compatibility & Compliance

This laser diode is intended for integration into OEM systems—not standalone instrumentation—and must be operated only within its absolute maximum ratings (per datasheet Rev. 2.1). It complies with key international regulatory frameworks including IEC 60825-1 (laser safety), EN 61326-1 (EMC for laboratory equipment), and ISO 14001 environmental management standards. While not certified for medical device use out-of-the-box, the device meets foundational requirements for inclusion in Class IIa/IIb diagnostic systems under ISO 13485 when embedded in a fully validated host platform. Operation requires full compliance with ANSI Z136.1–2022 for safe use of lasers in research and industrial environments. Humidity control (< 40% RH) and particulate-free ambient conditions (ISO Class 5 cleanroom or equivalent sealed housing) are mandatory to prevent facet contamination or moisture-induced catastrophic optical damage (COD).

Software & Data Management

As a bare semiconductor component, the BAD1320010CM003WXXXX does not include embedded firmware or digital interfaces. System-level integration necessitates external current drivers (e.g., low-noise, temperature-stabilized benchtop LD controllers) and thermoelectric coolers (TECs) with closed-loop feedback. For traceable calibration and quality assurance, users are advised to implement data logging compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and secure storage—when used in GMP-regulated environments such as biophotonics R&D labs or contract manufacturing organizations (CMOs). Innolume provides comprehensive characterization reports (L-I-V, spectral, far-field) in standardized CSV and PDF formats for metrological traceability.

Applications

• Optical coherence tomography (OCT) light sources for ophthalmic and dermatological imaging systems
• Pumping of thulium-doped or holmium-doped fiber amplifiers in mid-IR generation setups
• Gas sensing via tunable diode laser absorption spectroscopy (TDLAS) targeting H₂O, CH₄, and CO₂ absorption lines near 1320 nm
• Seed source for master oscillator power amplifier (MOPA) architectures in ultrafast fiber laser systems
• Calibration reference in NIR radiometry and photodetector responsivity testing per NIST-traceable protocols

FAQ

What is the recommended heatsink thermal resistance for stable 2 W operation?
For sustained CW output at 2 W, the total thermal resistance from junction to ambient must remain ≤ 0.5 K/W. This typically requires a water-cooled heatsink with surface flatness < 1 µm and interfacial thermal resistance < 0.05 K·cm²/W when using indium foil.
Can this laser be driven in pulsed mode?
Yes—pulse operation up to 100 ns pulse width and 1 MHz repetition rate is supported, provided peak current remains within absolute maximum ratings and duty cycle does not exceed 10% to avoid thermal runaway.
Is electrostatic discharge (ESD) protection built into the package?
No. The device is Class 1A ESD-sensitive (HBM < 250 V). External ESD mitigation—including grounded workstations, ionizers, and wrist straps—is mandatory during assembly and probing.
Does Innolume provide aging data or reliability test reports?
Yes—accelerated life-test data (5000 h @ 85°C case temperature, 1.8 W output) demonstrating < 5% power degradation is available under NDA upon request.
What collimation optics are recommended for free-space coupling?
A 3 mm focal length aspheric lens (NA 0.65) with AR coating at 1320 nm is optimal for minimizing astigmatism and achieving M² < 30 in the slow axis.
