Today I installed the razor blade that cuts the beam vertically and measured the pump beam parameter.
The blade is at 90 mm from the edge of the breadboard and I used about 100 mW of input power.
I measured a waist size of 22 um at 58 mm (in Manuel's unit) while we expect 36 um at 61 mm.
I started the tuning of the telescope but it is not concluded yet.
