Drive circuits for laser diodes are either automatic power control
(APC)
circuits that maintain a constant light output power or automatic current
control (ACC) circuits that maintain a constant current.
The output power and wavelength of the laser diode can be affected by
the changing of temperature. APC circuits provide a constant light output
power despite variations in ambient temperature. If you have a DC power
supply which provides you an accurate and stable DC voltage. You may use
this APC circuit board without voltage regulator.
APC with voltage regulator circuit enhances the function of APC circuit.
It provides constant output power when the input voltage is between 2.8V
DC and 6V DC.
Even with constant current drive, the output power of laser diodes varies
with ambient temperature. However, a slight change of output power during
operation is acceptable for many applications such as laser pointer and
laser sight. In addition, battery is the most popular power source for
laser diode module. In this case, the output power of laser will go down
caused by the battery voltage decreased. The ACC circuit will provide the
laser diode with constant current and stable output power.
