    • HHL-Packaged Terahertz Quantum Cascade Laser

    The HHL-packaged terahertz quantum cascade laser is a high-performance terahertz laser source using compact high heat-load packaging technology.The product employs four-stage thermoelectric cooling and water-cooling technology. It can achieve terahertz laser output without the need for a traditional cryostat or deep-cooling media such as liquid nitrogen and liquid nitrogen [sic]. By integrating a patch-array antenna, it achieves low-divergence, single-lobe surface emission and offers advantages such as a compact structure, good beam directivity, and convenient system integration. The product uses an industrial-standard HHL hermetic package and is suitable for fields including terahertz spectral analysis, scientific research, imaging inspection, and precision optoelectronic system development.

    Product features：Non-deep-cooling；High-efficiency directional emission；Compact standard package；Stable and reliable design

    Part Number：MP-QCL-HHL-76.9-2-Y

    Application area：Terahertz spectral analysis | Terahertz imaging inspection | Scientific research and experiments | Precision optoelectronic system integration
