About AdValue Photonics Inc
Advalue Photonics is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Tunable Single Frequency Fiber Laser for Fiber Optic Sensor Systems. The abstract given for this project is as follows: In this proposal, we propose to demonstrate and build a widely tunable, low phase noise, narrow linewidth, single frequency fiber laser by developing an innovative Er/Yb-co-doped polarization maintaining (PM) single mode fiber. Such a fiber laser is needed for advanced fiber optical towed array sonar systems. In Phase I, we will design and fabricate this new fiber, demonstrate fixed wavelength low phase noise narrow linewidth single frequency fiber laser with linewidth of less than 3KHz, demonstrate wavelength tuning range of greater than 20nm, and conduct an analysis on the reliability and maintainability benefit of this proposed technology over current fixed frequency low noise laser. Successful demonstration of such a fiber laser will enable many new commercial and military applications.Advalue Photonics is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Terahertz Source and Spectrometer. The abstract given for this project is as follows: We propose to develop a fiber-based, high power, narrow linewidth, and tunable THz source to implement a novel THz spectroscopy system by leveraging our proprietary fiber laser technology. This proposed high power fiber-based THz source will be generated by using a nonlinear crystal based on difference-frequency generation (DFG) pumped by high power pulsed fiber lasers in MOPA with high repetition rate (quasi-CW), which will reach a high power of ~ 1 W, a widely tuning range of 0.1-7 THz, and a narrow linewidth of 50-100 MHz. This proposal will use an external power cavity to enhance the conversion efficiency of parametric THz generation. The spectral resolution for the proposed THz spectrometer can be better than 200 MHz due to narrow linewidth, frequency accuracy, fine wavelength tuning step, and low phase noise for the proposed fiber-based THz source.Advalue Photonics is a company that received a Department of Defense SBIR/STTR grant for a project entitled: Handhold High Resolution Visual Detector for Ceramic Armor. The abstract given for this project is as follows: We propose to design and implement a novel field portable THz detector for examining vehicle armor panel and body armor based on the high frequency (0.5-10 THz) and high power THz source and a commercial high resolution focal-plane array (FPA) camera. The crucial high frequency THz source will have subwatt-level power that is sufficient to penetrate thick armor ceramics for high resolution imaging, which will be designed and implemented. The proposed field portable THz detector will provides unique and high resolution diagnostic tools for identifying and locating the non-ballistic impacts of vehicle armor panel and body armor in the field. Furthermore, it will be the most promising detector for homeland security, especially for the remote sensing and imaging of hazardous materials, such as improvised explosive devices (IED), drugs and poison chemicals due to its high power, tunable high frequency and high resolution.Advalue Photonics is a company that received a Department of Defense SBIR/STTR grant for a project entitled: High Power 2.1 Micron Fiber Laser. The abstract given for this project is as follows: High energy laser can provide a tremendous benefit to the army for area protection against rockets, artillery, and mortars (RAM). There is concern about high energy laser systems potentially causing collateral eye damage due to scattering off of target surfaces. We propose to develop innovative high efficient high power 2.1 micron fiber laser that is scalable to power levels of greater than 10kW. This new fiber laser is retina safe which significantly reduces the possibility of permanent eye damage due to laser scattering, and exhibits good atmospheric transmission which is necessary to use laser to provide protection against rockets, artillery, mortars (RAM), and other potential threats. We will design new glass composition to host high rare-earth doping concentration to generate extremely efficient fiber laser, characterize the spectroscopic properties to identify the optimum doping concentrations, design and fabricate large core double cladding single mode fiber, and demonstrate efficient fiber laser. Slope efficiency of 65% is expected. Successful development of such innovative highly efficient high power fiber laser with output power of 10 kilowatts level would revolutionize the fiber laser development and enable many new applications.
