Can applying more voltage increase the output power of a laser diode module?

Almost all our laser diode modules are preset internally to accept only a certain amount of voltage in order to operate the laser. "Power variable" lasers however typically operate on a 3-wire lead principle, where the additional lead can be used to adjust the internal potentiometer by varying the voltage. The other two electrical leads are the common positive (red) and negative (black) used for operating power. The case housing is typically set to a positive potential, which should be taken into consideration in order to properly ground the housing and not damage the laser. Power supplies should be selected to run at the lowest voltage value in order to extend lifetime. Heat sinks are recommended and must be used if operating near maximum voltages.
