Many laser diode packages include a second photo diode to monitor the output of the laser. One of the most commonly used and important laser diode specifications or characteristics is its L/I curve. Application is going to define the major parameters of a laser diode: wavelength, power, and package style.

The light-current-voltage (L-I-V) sweep test is a fundamental measurement that determines the operating characteristics of a laser diode (LD). Laser Diodes are current driven devices whose response (mA of current input to produce a mW of light output) can change significantly with temperature, age, and other effects. Laser diodes (LD) are semiconductor devices that convert electrical energy into high-power optical energy. The semiconductor laser developed by LD-PD is currently operating for 7X24 hours in different application areas of its partners.
