Abstract: (2099 Views)
In this paper, we investigate the effects of temperature on experimental parameters of laser diodes such as threshold voltage , current and optical power. In our setup, we drive a 658nm laser diode with a typical power of 150mW by a stable current source and temperature stabilizer. We plot the P-I and V-I curves and calculate the threshold current by fitting a linear trendline. Based on the results, optical power decreases, and threshold current increases with the increase of temperature.
Keywords: Diode Laser, Threshold Current, Temperature Stabilization, Threshold Voltage, Power Meter.
