Algebra Intelligent Tutoring System (ITS) for at-risk students

Not Available Sensors Unlimited will grow, fabricate and test Master Oscillator Grating Coupled Power Amplifier (MO-GCPA) lasers designed to operate with diffraction-limited beam divergence up to 5 W CW power in the 0.97-1.1 (magnetic moment)m wavelength range. The goal of this program is the delivery of the relevant basic material and device characterization necessary for the design of this new type of MOPA laser along with the MO-GCPA lasers operating at 5 W output power in a single spatial mode. The motivation for MO-GCPA device development is the commercial potential of diffraction-limited beam high power sources for free-space communications, laser radar applications, pumping and material processing systems. In order to achieve this goal, Sensors Unlimited will use the services of Sarnoff Corporation to grow low-loss broadened waveguide InGaAsP/InGaP laser structures and fabricate on their case high-power lasers with diffraction-limited beams. In Phase I we will design and test the main element of MO-GCPA lasers which is the master distributed Bragg reflector section with coupling grating. Data from these measurements will prove invaluable for the fabrication and testing of further designs in Phase II of the program.
