Beam profile
Result in Fig.2.
Beam Profile -> I will consider the optimization of number of frames and integration time
Power measuremet -> I selected 660um for this measurement
- Looking at the beam profile, I guess the number of frames 8 is too small. And the exposure time seems not appropriate. Let's revisit the measurements later on.
- To comfirm things, it might be better to put a description clearly what wavelength was set when the power was measured, as this PD-type power meter is sensitive to the choice of wavelength.
(For taking care of signal-to-noise ratio (SNR) on the beam profile measurement, I guess the gain should be fixed to 1 (or 0 dB), while the exposure time should be properly set to improve the SNR, depending on the profissional sense of the experimentalist (in short, needs to consider in-situ wise).
