Phase 1 SBIR
ABSTRACT: Chalcogenide glass fibers are commercially available and are used for delivery of mid-infrared wavelengths (1.5um to 6.5um). These fibers allow compact, robust and low-weight laser platforms designs. Laser systems in high-power and high-stress environments find their reliability and performance limited due to free-space optical compo...
Phase 1 SBIR
Beam combining devices are extensively used to achieve power levels that cannot be reach by the use of just a single laser. To achieve beam combination these devices commonly employ free-space optical components, like mirrors, gratings and lenses. The use of free-space optics has several issues such as sensitivity to thermal and vibration induce...
Phase 1 STTR
Institution: The Ohio State University
ABSTRACT: Laser source technology in the mid-infrared region, 2um to beyond 10um, is progressing rapidly. ?Quantum cascade laser (QCL) is one of these new sources, which cover the whole mid-infrared spectrum with high-power and good wall-plug efficiencies. ?Due to the micron sized and non-circular cross-section of the active region, the laser be...
Phase 2 STTR
Institution: University of North Carolina Charlotte
Chalcogenide glass fibers are extensively used for delivery of mid-infrared (2-5 micron) laser wavelengths. They are needed for development of next-generation Directed InfraRed CounterMeasure (DIRCM) systems. Replacing the bulky free-space delivery system with fiber will reduce the weight and size of these systems enabling the installation in ve...
Phase 2 SBIR
Future military and commercial laser-based systems will incorporate high peak energy ultra-short pulse lasers (USPLs) operating in the near or mid-infrared. These USPL will require a beam delivery system (BDS) for use within defensive systems. Step-index optical fibers have been used as BDSs with excellent results at low power levels. However, t...
Phase 1 STTR
Institution: University of North Carolina Charlotte
Chalcogenide glass fibers are extensively used for delivery of mid-infrared (2 to 5 micron) laser wavelengths. They are needed for development of next-generation directed infrared countermeasure (DIRCM) systems. These new systems will have a reduction of both weight and size allowing their installation in vehicle and aircraft with stringent weig...
Phase 2 SBIR
ABSTRACT: Infrared cameras for thermal imaging applications can operate between 2-14 microns. These cameras produce a thermal image using two-dimensional arrays of infrared detectors (such as ferroelectric detectors or microbolometers). Some critical military applications (such as spatial analysis of combustion processes in turbines combustors...
Phase 1 SBIR
Compact high power (>100 W) mid-infrared (2-5 microns) lasers are highly desired for military applications, such as infrared counter measures (IRCM). Semiconductor lasers, such as quantum cascade lasers (QCLs), are efficient compact sources that operate in the desired wavelength range. However, these lasers are currently limited in output power ...
Phase 1 SBIR
High power midwave infrared (2 {5 Ým) lasers are currently used in infrared countermeasure (IRCM) systems. The objective of this SBIR is to develop high efficiency laser beam delivery system. Current beam delivery methods for IRCM systems are manufactured from free-space optics or midwave multimode fibers. Free-space beam delivery has limite...
Phase 1 SBIR
Future military laser-based defensive systems (LBDSs) will incorporate high peak energy (~1 mJ) ultrashort pulse ( The proposed work will demonstrate the feasibility of developing an innovative mid infrared HC-PBG fiber. The fiber will be designed with high confinement (> 99%) to enable ultrashort pulses (
