LASER POWER ADJUSTMENT PROCEDURE
1. Connect 1 µF capacitor (Cx1) between Pin 1 and Pin 2.
2. Connect 20 ~ 50 K ohm variable resistor (Rx1) between Pin 2 and
Pin 3.
3. Set V
cc
to the designed value.
4. Adjust Rx1 to obtain the desired output power.
5. Laser Safety Precautions
(1) Do not increase V
cc
value when the laser module is
working near the maximum power. That is to protect laser
from overdriving condition and make sure power is under
3 mW.
(2) Do not operate the device above the maximum rating condition, even momentarily. It may
cause unexpected permanent damage to the device.
