	Today I discovered a new way to profile a beam at high power. I used a regular 1064nm mirror. The mirror gives a 99.99% reflection at 45 degrees. So I used the mirror in between CCD camera and the AOM at some angle less than 45. In this way transmission through the mirror can be controlled. its highest at 0 and lowest at 45. In between desired transmission can be achieved. I received a transmission of 99mW at 4.10W at the angle of roughly 15 degrees. I used the CCD with 3+3+2 OD filters. This setup does not distort the beam profile too much and it’s safe for the OD filters. We got some good pictures through this process; the link is presented below.
