Thecircuit is a GaAsP LED which is quickly switch-on to supply required low driven impedance.The LED can be used as high speed pulse lamp-house in fiber or other light.Q1 supplys volts d.c. and information for Q3(follower).Q2 detects output current, and limits it at about 30mA.The max switch-on time is 12ns.
