What's Happening?
A recent study has demonstrated a method for stabilizing laser power using conservation laws within an acousto-optic modulator (AOM). The experimental setup involved a semiconductor laser and a photoelectric control system, where laser power was regulated through a frequency regulator and a series of photodetectors. The study focused on the diffraction efficiency of the AOM, which is sensitive to temperature fluctuations. To address this, a temperature control system was implemented using a TEC cooling plate and an NTC thermistor. The research revealed that the transmission of the AOM crystal increases with temperature, and a PID control algorithm was used to adjust the diffraction beam power dynamically. The findings were validated through experiments that measured the relationship between diffraction beam power and sampling beam power, confirming the theoretical conservation law.
