The telescope to adjust the beam size was made only using one lens with very long focal length (1 meter)
it is placed a distance of 40 cm from the collimeter and 1 meter from the center of the beam waist between the planar mirrors.
This way the two beam (of laser and cavity) have the shape when they propagate

The beam waist of the Koheras CW laser after the collimater is bigger than the Waist required for injection inside the cavity at M1.
A Telescope is to be made to match the two beams.
Details will be added ......
