Laser diodes have different operating modes, such as continuous (CW), pulsed, and modulated modes. In this article, by modulating a pulse wave with a specific frequency (f) and duty cycle, we change the output current and frequency of laser diode. So the laser diode output changes to modulated mode. Because of the structure of semiconductor lasers and the short duration of injecting current to the active region of laser, the electrical characteristics of the laser will be changed so that laser diode can be overdriven. In this experiment, we will show the effects of frequency on laser diode efficiency.
