Design and test of fast laser driver circuits
WebI am working on a design that incorporates an OPA835 to control the current pumped into a semiconductor laser diode. The feedback of the control loop utilizes a Si photodiode that is part of the laser diode packaging (schematic below). When I breadboard this circuit and use a DC reference of 800 mV, the op amp output is oscillating (the ...
