Embodiment Construction
[0029] Such as figure 1 As shown, the device of the present invention is composed of a laser 1, a beam splitter 2, a variable attenuation sheet 3, a reflector 4, a spectrometer 5, a detector 6, and an optical power meter 7. The detector 6 generally adopts a photodiode or a photomultiplier tube detector.
[0030] The specific implementation of the method of the present invention is as follows: figure 1 As shown, the laser 1 adopts a continuous semiconductor laser with an output wavelength of 1060nm. Because it is in the invisible band, one visible light can be introduced during the experiment as an auxiliary optical path to facilitate subsequent optical path adjustment; ensuring that the feedback light intensity can meet the requirements of the laboratory If necessary, try to increase the transmission ratio of the beam splitter to make the output light power as large as possible. Through the analysis of experimental data, the transmission ratio of the beam splitter is selected to...
