Mid-Infrared Laser Beam Combining Module for Infrared Countermeasure Application

There is a compelling need for scaling the output of mid-infrared (Mid-IR) lasers to much higher power, brightness, and energy, particularly for infrared countermeasure (IRCM) application. In Phase I of this program, we demonstrated a proof-of-concept wavelength beam combined (WBC) laser constructed with QCL source emitters. We propose a Phase II multi-wavelength-band laser module that increases the output Mid-IR power and brightness from a very compact laser module that is compatible with the Modular Open Systems Approach (MOSA). This demonstrator will establish both the power scalability of the WBC configuration and the ability produce laser modules using WBC technology in multiple IRCM wavebands.
