This proposal describes a new approach to laser diode drivers which combines the unique advantages of three key technologies. The innovative approach will extend the performance capabilities of laser diode systems to greater than 200 A peak pulse current, less than one nanosecond rise time, at greater than 10 KHz repetition rates. Not customarily used in laser diode drivers, the unique combinati ...

The miniaturization of the laser diode, power switches (MCT, IGBT, etc.), the drastic increase in the number density of transistors on a monolithic chip and the capability to drive these chips at very high power ratings and clock speeds has increased the demand for the devices. However, such high performance can be extracted only over short time pulses because the devices produce a moderate amoun ...

Event Tracking Service (ETS) proposes to study the feasibility of developing a low cost ($50), self-contained, dual use, miniature, credit card size Environmental Measurement Device (EMD) to sense and log shock, vibration, temperature, and humidity. The device would be readily expandable to monitor other parameters. Our low power architecture includes 3V off-the-shelf CMOS electronics, a low power ...

Portable, ultra-high sensitivity gas sensors for the detection of combustion products in plumes are urgently needed to accelerate efforts to reduce the environmental impact of combustion processes in both military and civilian applications. Innovative Lasers Corporation (ILC) proposes to develop a portable, light-weight gas sensor based on intracavity laser spectroscopy (ILS) with the ultra-high ...

Testing of sophisticated integrated avionics equipment installed on aircraft, requires high capacity data to be transferred from the signal source to the aircraft. The aircraft performance and safety depends on the quality of the test. Quality and cost of the test depend on speed and reliability of the communication link. For the test purity, cable fiber optic link, or electromagnetic type of c ...

Conventional composite processing techniques are presently unable to fabricate Al1O3-fiber reinforced y-titanium aluminide matrix composites based on low cost, small diameter ( 5-20um) fibers. The primary problem is one of infiltration of the matrix in between the fibers without any degradation in fiber properties. Although pressure casting would be a low cost processing approach, the severe che ...
