Sample plots from high-power laser
diode characterization system. It was built for
testing bar type lasers (shown in picture). The test
system was designed for acquiring data at stable
temperature for repeatability. The setups could be
operated in a fully automatic mode with minimal input
from the operator. Different test systems were capable
of testing diodes in CW and QCW mode. CW test system
could go up to 100Amps and QCW systems could go up
150Amps (20% Duty cycle). CW test system was also
capable of acquiring Thermal Impedance data. Both CW &
QCW projects involved complete electronic assembly,
equipment selection, computer interfacing and a fully
automated test software. Additionally for QCW test
setup an interface for Avtech. Pulser was
designed and fabricated. Buffer amplifiers were also
designed and built to isolate high power pulse
subsystem from measurements systems. |
