10.26um DFB Quantum cascade lasers (QCLs) TDLAS Analyse Systems

10.26um High power DFB 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.

High performance QCLs

LD-PD Inc product line offers single mode Quantum Cascade Lasers (single mode DFB QCL) or broadband lasers (Fabry Perrot) between 4µm – 12µm (2500 cm-1 – 900 cm-1). Our lasers operate at room temperature, without a cryogenic system, in pulsed or continuous wave emission.And our DFB-QCL have two types for customer’s Choice:Low power Consumption and high power Consumption.
