Hi all,
a Darlington pair with two 2N2222 transistors were used to drive a laser diode working at 1.2A, however, there is about 100ns delay in the optical output as well as two or three times the pulse broadening wrt to the electrical signal. delay can be tolerated but not the optical pulse broadening.
is there a way it can be corrected somehow? is there a better circuit with other components i can achieve the same current and speed. ?
