Experimental Function Description
By measuring the power, voltage, and current parameters of the semiconductor laser, users can deeply understand its working characteristics under continuous output mode.
With the assistance of the Optical Multi-Channel Analyzer, accurately observe the spectral changes of the semiconductor laser under different injection current conditions: when the injection current is lower than the threshold, fluorescence emission can be observed; when the injection current is higher than the threshold, the spectral line changes generated by laser oscillation can be detected.
