hi all, I am trying to monitor the laser intensity at the output end of my MEMS device. I have a problem as I have to be able to see the output on a ccd camera, and measure the intensity at the same time. Currently, I first align using a ccd camera, remove it from the beam path, introduce a photodetector in the beam path, measure intensity, repeat the steps again and again for each measurement. This is an extremely tedious and time consuming process. Any suggestions on kind of optics I can use two get both measurements at the same time (CCD+photodetecotr) will be appreciated. I monitor the intensity at high frequencies of order 300Khz, thus have to use a silicon photodetector, CCD camera is only for visual alignment regards Vaibhav Mathur
