4.6um FP Quantum cascade lasers (QCLs) Testing Source

4.6um High power FP Quantum cascade lasers (QCLs) is developed by LD-PD INC in 2019.Our Quantum cascade lasers (QCLs) are intersubband semiconductor lasers emitting around a center wavelength ranging from the mid-infrared (4 – 12 µm) up to the terahertz domain. The QCLs proposed by LD-PD Inc are mid-infrared devices operating in pulsed or continuous-wave regime at room temperature. They can be either High power multimode (Fabry-Perot) or Narrow linewidth single-mode (Distributed FeedBack, or DFB) laser sources.We build Znse lense into the system to collimate the Laser beam.
