Abstract
In this research, a circuit design for square pulse generation was proposed by using microcontroller to generate pulse width modulation signal (PWM). The PWM signal, then, has generated the voltage for a laser diode of wavelength 650 nm. The frequency can be tuned approaching 0-5 MHz with the simplicity of the pulse width adjustment. The signals at the width of 130 x 10-9 s, 400 x 10-9 s, 600 x 10-9 s, 850 x 10-9 s, 1000 x 10-9s was examined to generate laser pulses. The heat in the pulse generator can be effectively controlled.
