Check the APC circuit (automatic power control) this circuit is composed of a transistor and an integrated. The APC circuit is inside the servo IC, a voltage level of approx. 2.8V- 3.2V this voltage level goes to the base of Tr. of the laser diode and this by its collector delivers a level of 2V that goes directly to the LD of the lens through the 16-pin flat in the transmitter is powered by 5V or 3.5V depending on the brand of the equipment, this voltage reaches the emitter through a resistance that usually is 10 homios.
