This is 1064nm 4W coherent compass laser, we are planning to use for optical tweezrs.
- Beam Profile at various powers
- Beam Profile at power below 3.5W, is same horizontally and vertically and the intensity over the spot looks homogeneous. It looks like the TEM00 mode only.
- Beam profile at power higher than 3.5W, is different vertically, so as the intensity over the spot. It looks like a combination of TEM00 and TEM01 mode. The presence of even higher order modes than TEM01 cannot also be denied.
