4730nm DFB Quantum Cascade Laser, HHL Package, Internal TEC

4.73µm DFB Quantum Cascade Laser Overview:

This Quantum Cascade Laser is fabricated with a distributed feedback waveguide. The edge-emitting diode is mounted in a sealed High-Heat Load package with window and internal TEC. The internal TEC stabilizes the laser diode temperature to provide stable and reliable output power and wavelength. The DFB waveguide provides single-frequency output, with SMSR of 30 dB. The maximum operating current is ~340mA, with a threshold current of 250mA. These QCL Lasers are available over the entire mid-IR spectrum, and are the ideal tool to apply to gas sensing, chemical detection, and R&D applications.
