    Laser diode driver oscillating

    Hi, I came across a circuit which can be used to drive a laser diode in continuous mode (CW) or modulated (<=100Khz). A BFR540 (NPN) transistor is used to drive the laser diode and a photodiode (inside the laser diode package) provides an output current based on the optical output power, which...
