Nishino,

I measured the beam profile of the green laser before the PCM. The beam widths are {0.091, 0.111} mm for {x, y}, the positions are at z={320, 257} mm from the starting point (z=0).

z=0 is 900 mm away from the PCM. Using these values, I derived the position of two lenses, f150 and f400, at z = 134 mm and 566 mm, achieving the best mode-matching of 93%.
